    NLTS Hamiltonians and Strongly-Explicit SoS Lower Bounds from Low-Rate Quantum LDPC Codes

    Full text link
    Recent constructions of the first asymptotically good quantum LDPC (qLDPC) codes led to two breakthroughs in complexity theory: the NLTS (No Low-Energy Trivial States) theorem (Anshu, Breuckmann, and Nirkhe, STOC'23), and explicit lower bounds against a linear number of levels of the Sum-of-Squares (SoS) hierarchy (Hopkins and Lin, FOCS'22). In this work, we obtain improvements to both of these results using qLDPC codes of low rate: - Whereas Anshu et al. only obtained NLTS Hamiltonians from qLDPC codes of linear dimension, we show the stronger result that qLDPC codes of arbitrarily small positive dimension yield NLTS Hamiltonians. - The SoS lower bounds of Hopkins and Lin are only weakly explicit because they require running Gaussian elimination to find a nontrivial codeword, which takes polynomial time. We resolve this shortcoming by introducing a new method of planting a strongly explicit nontrivial codeword in linear-distance qLDPC codes, which in turn yields strongly explicit SoS lower bounds. Our "planted" qLDPC codes may be of independent interest, as they provide a new way of ensuring a qLDPC code has positive dimension without resorting to parity check counting, and therefore provide more flexibility in the code construction

Brief is an artist whose recent work explores the way that language, thought and information relate to contemporary culture and the creation of self. In February, SLU hosted the 16th annual “Earthquakes Mean Business” seminar, which brought to campus hundreds of business and industry leaders, as well as emergency pre-paredness professionals and first responders, from around the region. Dr. Robert Herrmann, SLU’s Otto W. Nuttli Professor of Geophysics, was a featured speaker. He discussed earth-quake monitoring in the central United States. Undergraduate students at Saint Louis University feel more engaged than their peers at other research institutions across the country. That’s according to the 2009 National Survey of Student Engagement, released in November by the Carnegie Foundation for the Advancement of Teaching. { on campus } Photo by Chad Williams SLU reaches out to Haiti In the aftermath of the January earthquake in Haiti, Saint Louis University faculty, staff and student groups responded with a variety of efforts to as-sist the disaster-stricken country. Dr. Tim Rice, an associate professor of pediatrics and internal medicine, left in January for Haiti, leading a team of St. Louis-area health profes-sionals to care for victims of the earthquake. With him was Dr. Marie Miller (Grad ’06), a fourth-year SLU medical student. Rice’s SLU colleagues — Dr. Robert Flood, director of the division of emergency medicine at SSM Car-dinal Glennon Children’s Medical Center, and Dr. Christian Paletta, profes-sor and chief of the division of plastic surgery — went on similar trips. In addition, Doisy College of Health Sciences students and faculty orga-nized a toiletry drive for victims of the Haiti earthquake. Donated items were distributed by Randolph World Ministries Inc. Run by Dr. Tim Randolph, associate professor of clinical laboratory science, the nonprofit organization establishes and supports laboratories in Haitian medical clinics. In addition, SLU’s Micah Program and Doerr Center for Social Justice Education and Research spearheaded a benefit concert at Busch Student Center. The program featured four bands, and 100 percent of the 5,000 in proceeds was donated to Haitian relief. Collections to raise funds for Haiti also have been held at the Madrid Campus, during Mass at St. Francis Xavier College Church and at Billiken basketball games. SLU is a good neighbor Saying that Saint Louis University reflects the best of the Jesuit devotion to the inner city poor, a national survey has ranked SLU among the top 25 urban colleges and universities considered “good neighbors.” Saviors of Our Cities: A Survey of Best College and Uni-versity Civic Partnerships was released during the Coalition of Urban and Metropolitan Universities conference last fall. Saviors of Our Cities highlights SLU’s involvement in the Center of Research Technology and Entrepreneurial Exchange, better known as CORTEX. The science and technology corridor is establishing St. Louis as a hub for biotech research and development. The rankings also single out the University’s nationally recognized Micah Program, a faith-based living and learning initiative, as well as SLU’s Doerr Center for Social Justice Education and Research, which provides funds for research and student engagement projects that largely focus on the urban poor. SLU funded for prevention research Anew Saint Louis University-Washington University in St. Louis initiative that studies innovative ways to prevent chronic disease and improve health has received a five-year, $8 million grant from the Centers for Disease Control and Prevention. The Prevention Research Center in St. Louis, one of 35 programs at academic institutions in 25 states, examines how people and their com-munities can avoid or counter the risks of chronic illnesses such as heart disease, asthma and diabetes. The collaboration between Saint Louis University School of Public Health and Washington University Schools of Medicine and Social Work is Missouri’s only CDC-funded Prevention Research Center. This is the 15th year the SLU School of Public Health has been involved in the CDC’s Prevention Research Centers Program. The center has established partnerships with community-based coali-tions, the Missouri Department of Health and Senior Services, and a variety of academic collaborators to reduce obesity and prevent chronic diseases in low-income, rural parts of the state. Tait named VP of research Dr. Raymond Tait, professor of neurology and psychiatry, was promoted to vice presi-dent of research in February. In this new role, he works with administrators, faculty and staff in promoting Saint Louis University research. He also seeks to further enhance SLU’s research pro-grams by working closely with private industry and governmental agencies, as well as other educa-tional and research institutions. Tait joined the SLU faculty in 1982 as an assistant professor of psychiatry and human behavior. In 1995, he left the full-time faculty to become director of functional rehabilitation service at the SSM Rehabilitation Institute. During this time, he continued to teach at SLU as an associate clinical professor in psychiatry. He returned to the full-time faculty in 1998. He also holds an adjunct appointment in SLU’s Gnaegi Center for Health Care Ethics. MI CASA ES SU CASA: Casa de Salud, a new wellness clinic for the underserved Hispanic community in St. Louis supported by Saint Louis University, began seeing patients Jan. 18. Located at the corner of Compton and Chouteau avenues, the clinic engages volunteers to provide basic health and wellness care for its clients. Casa de Salud, which means “House of Health,” offers service opportunities to family doctors, internal medicine physicians, emergency medicine doctors and nurse practitioners, among others. STANDING FOR LIFE: During its annual trip to the national March for Life in Washington D.C., SLU’s Students for Life group (profiled in the fall issue of Universitas) received the 2009 Community Outreach award from Students for Life of America. About 50 SLU students traveled to the na-tion’s capital in January for the march. 19 Student organizations on campus dedicated solely to service and issues of justice 411 Agencies where SLU students volunteer on a regular basis 317 SLU students who are mentors with the Big Brothers, Big Sisters program 311 Members of the SLU chapter of the national service fraternity Alpha Phi Omega, making it the largest in the nation, per capita 672 Children from low-income families who had school supplies provided last fall through the annual SLU school supply drive 5,264 Hours spent each year cooking and delivering meals to low-income people through SLU’s Campus Kitchen BY THE NUMBERS: With SLU’s Center for Service and Community Engagement Photo by Chad Williams Submitted photo Elie Wiesel speaks to record crowd Elie Wiesel, an internationally recognized human rights advocate and Holocaust sur-vivor, told an audience of 2,800 people gathered to hear him speak at Saint Louis University Dec. 1, about the power of empathy. “We cannot allow ourselves not to feel the pain of others,” Wiesel said. “We can’t give in to indifference.” Wiesel, who received the Nobel Peace Prize in 1986 for his fight against global oppression, told stories and gave fatherly advice as he encouraged the crowd to find strength together, as part of a larger community. He described his goal as being a matchmaker who brings people together to spark meaning-ful relationships. “Whatever you do in life,” he said, “always think higher. Feel deeper. Be sensitive. Be sensitive to each other — to each other’s pain, to each other’s joys and each other’s fears.” The event was sponsored by the Great Issues Committee.

The team earned an automatic berth into the tournament by claiming the Atlantic 10 Confer-ence Championship Nov. 15 with a victory against Dayton. It was the first A-10 Tournament championship for the Billikens since joining the league in 2005. Since 1991, the Billikens have captured nine conference championship titles. The team opened the 2009 NCAA Men’s Soccer Tournament in November with a 2-1 vic-tory over Missouri State at Hermann Stadium. It was the second year in a row SLU earned a victory in the first round of the NCAA Tournament. However, the Billikens lost in overtime to No. 8 seed Tulsa in the second round of the tournament. Despite the loss, it was a successful season for the team, with six Billikens earning All-Conference honors. Senior Tim Ream was voted Defensive Player of the Year and named to the A-10’s first team, while freshman Alex Sweetin earned Rookie of the Year honors. Sophomore Mike Roach was named second-team All-Conference, while senior Josh Aranda earned honorable-mention recognition. Aranda also joined Roach and Ream on the A-10 All-Champion-ship team. Freshman Benny Estes and Sweetin were voted to the All-Rookie team, while keeper Ross Kaufman earned a spot on the All-Academic team. Volleyball makes third NCAA Tournament appearance The SLU volleyball team finished its 2009 campaign with a 24-8 record and made its third NCAA Tournament appearance in the last four years. SLU entered the tournament ranked 22nd in the nation and had the 18th-best hitting percentage in the NCAA. But the Billikens lost to Wichita State in the opening round. It was the team’s first NCAA Tourna-ment at-large bid, after earning automatic bids in 2006 and 2008 by winning the Atlantic 10 Championship. The 2009 Billiken volleyball season will be remem-bered in the record books. { billiken news } BILLIKEN BEAT In January, Billiken men’s soccer senior defender Tim Ream was drafted by the New York Red Bulls in the MLS SuperDraft. He was the 18th player selected overall and the second player taken in the second round. In December, Ream was named a National Soccer Coaches As-sociation of America third-team All-American. His All-American honor is the 75th in SLU men’s soccer history. Ream played in all but one game during his four-year Billiken career. SLU head volleyball coach Anne Kordes re-ceived the 2009 Carl O. Bauer Award presented by the Missouri Athletic Club. The award, which was established in 1978, is presented annually to the top amateur sports figure in the St. Louis area. Kordes has guided the SLU volleyball pro-gram to three NCAA Tournament appearances and Atlantic 10 regular-season titles in the last four seasons. She has been named A-10 Coach of the Year three times. Dan Donigan has resigned as SLU’s head men’s soccer coach. He has accepted the same position at Rutgers University in his native New Jersey. Donigan came to SLU in 1997 and served as an assistant for four seasons under former coach Bob Warming. He was named head coach at SLU in 2001 after serving four seasons as an assistant. During his nine-year head coaching tenure, the Billikens posted a 118-42-23 record and made seven NCAA Tournament appearances. A national search for a new soccer coach is under way. The 2009 Billiken softball squad was recog-nized as a National Fastpitch Coaches Associa-tion Division I “girls got game” All-Academic team. SLU came in at No. 37 with a 3.292 GPA to lead all Atlantic 10 Conference schools. The Billikens swept Atlantic 10 Coach, Player and Setter honors for the second straight season. McCloud merited Co-Player of the Year recognition, and Roth captured an unprecedented third A-10 Setter of the Year award. Head coach Anne Kordes was voted Coach of the Year. Fonke landed on the A-10 first team for the second straight season, while junior Megan Boken picked up second-team plaudits. Senior Whitney Behrens achieved honorable mention status. Behrens and Roth also were named to the All-Academic squad. The team had three players achieve All-America status. Seniors Bridget Fonke, Sammi McCloud and Whitney Roth picked up AVCA All-America honorable mention honors. It is the second straight season that the trio received the distinction. SLU’s five seniors leave as the third-winningest class in program history. SLU put together four straight 20-win campaigns for just the second time.

    Sparse Cuts in Hypergraphs from Random Walks on Simplicial Complexes

    Full text link
    There are a lot of recent works on generalizing the spectral theory of graphs and graph partitioning to k-uniform hypergraphs. There have been two broad directions toward this goal. One generalizes the notion of graph conductance to hypergraph conductance [Louis, Makarychev - TOC'16; Chan, Louis, Tang, Zhang - JACM'18]. In the second approach, one can view a hypergraph as a simplicial complex and study its various topological properties [Linial, Meshulam - Combinatorica'06; Meshulam, Wallach - RSA'09; Dotterrer, Kaufman, Wagner - SoCG'16; Parzanchevski, Rosenthal - RSA'17] and spectral properties [Kaufman, Mass - ITCS'17; Dinur, Kaufman - FOCS'17; Kaufman, Openheim - STOC'18; Oppenheim - DCG'18; Kaufman, Openheim - Combinatorica'20]. In this work, we attempt to bridge these two directions of study by relating the spectrum of up-down walks and swap walks on the simplicial complex, a downward closed set system, to hypergraph expansion. More precisely, we study the simplicial complex obtained by downward closing the given hypergraph and random walks between its levels X(l), i.e., the sets of cardinality l. In surprising contrast to random walks on graphs, we show that the spectral gap of swap walks and up-down walks between level m and l with 1 < m ⩽ l cannot be used to infer any bounds on hypergraph conductance. Moreover, we show that the spectral gap of swap walks between X(1) and X(k-1) cannot be used to infer any bounds on hypergraph conductance. In contrast, we give a Cheeger-like inequality relating the spectra of walks between level 1 and l for any l ⩽ k to hypergraph expansion. This is a surprising difference between swaps walks and up-down walks! Finally, we also give a construction to show that the well-studied notion of link expansion in simplicial complexes cannot be used to bound hypergraph expansion in a Cheeger-like manner

    Palestinian and Israeli Nonviolent Resistance to the Israeli Occupation

    No full text
    Despite the long history of nonviolent campaigns by Palestinians challenging both British and Zionist colonialism, culminating in the overwhelmingly nonviolent first intifada (1987-93) and the present struggle against the Israeli occupation, this aspect of the Palestinian resistance is vastly under-reported. With her recent interview-based book, Kaufman-Lacusta will highlight non-violent resistance by both Palestinians and Israelis to the Israeli occupation along with ways US citizens can support this resistance.
