A proposal for replicating Evanschitzky, Baumgarth, Hubbard, and Armstrong's "Replication research's disturbing trend" (Journal of Business Research, 2007)
No full textThis paper is about how the author proposes to replicate Evanschitzky, Baumgarth, Hubbard, and Armstrong's "Replication research's disturbing trend" (Journal of Business Research, 2007). This is because estimating the incidence of published replication research and its outcomes must be continued

Realization of the bond order wave (BOW) phase of extended Hubbard models in Rb-TCNQ(II)
No full texta b s t r a c t Rb-TCNQ(II) is shown to be a realization of the BOW phase of half-filled extended Hubbard models. The BOW phase has a regular array of sites with inversion (C i ) symmetry, a finite magnetic gap E m and broken electronic C i symmetry. The phase is conditionally stable against dimerization for linear electron-phonon (e-ph) coupling. At 100 K, Rb-TCNQ(II) crystals have regular TCNQ À stacks at C i centers, negligible spin susceptibility that indicates finite E m , and infrared (ir) spectra that indicate broken C i symmetry. The 100 and 295 K crystal structures rule out a dimerization transition around 220 K that had previously been inferred from magnetic and ir data
Law, sex and the city: Regulating sexual entertainment venues in England and Wales
No full textPurpose – This paper aims to explore how municipal law, in its various guises, serves to police the boundaries of acceptable sexual conduct by considering how Sexual Entertainment Venues (SEVs) in British cities are controlled through diverse techniques of licensing and planning control. Design/methodology/approach – The paper describes the emergence of permissive new licensing controls that provide local authorities considerable control over SEVs. Licensing decisions, judicial review cases and planning inspectorate adjudications since the inception of the new powers are examined to explore the logic of judgements preventing SEVs operating in specific localities. Findings – Through analysis of case studies, it is shown that local authorities have almost total discretion to prevent SEVs operating in specific localities, particularly those undergoing, or anticipated to be undergoing, redevelopment and regeneration. Originality/value – This paper offers unique insights on the “scope” of municipal law by highlighting how land uses associated with “sexual minority” interests are regulated in the interests of urban regeneration, redevelopment and restructuring
Nonperturbative solutions to the Hubbard Model, 1987
No full textNonperturbative solutions to the Hubbard model are found by using the functional derivative method. A system of closed equations is obtained for the Green's functions of the Hubbard model. Exact expressions for the self-energy are derived which involve only first order functional derivatives. A scheme is proposed for systematically calculating self-energy corrections. We apply the solution to finite rings of two and four lattice sites and compare to the results of numerical calculations on these systems
Special Collections, Primary Resources, and Information Literacy Pedagogy
No full textLiterature suggests that teaching Information Literacy (IL) as an intellectual framework, rather than a set of computer-based tools, can be challenging for numerous reasons. At the same time, other articles describe the unique value of using hands-on investigations of special collections materials to facilitate the development of critical thinking skills and IL in discipline-specific contexts for upper-level students. This article reports on a collaboration between an IL instructor and a special collections librarian to create a hands-on special collections experience for entry-level IL students. We found that exposing these students to these materials can improve their IL and research skills. We explain our methods for designing and assessing such class sessions, and report on our results with students

Bragg spectroscopy of a superfluid Bose-Hubbard gas
No full textBragg spectroscopy is used to measure the excitations of a trapped, quantum-degenerate gas of Rb-87 atoms in a three-dimensional (3D) optical lattice. The measurements are carried out over a range of optical lattice depths in the superfluid phase of the Bose-Hubbard model. For a fixed wavevector, the resonant frequency of the excitation is found to decrease with increasing lattice depth. A numerical calculation of the resonant frequencies based on Bogoliubov theory shows a less steep rate of decrease than the measurements.http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000281279200005&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701Physics, MultidisciplinarySCI(E)EI28ARTICLEnull1

Quantum gas microscopy of the anyon-Hubbard model
No full textLow-dimensional quantum systems can host anyons, particles with exchange statistics that are neither bosonic nor fermionic. However, the physics of one-dimensional (1D) anyons remains largely unexplored. Using ultracold bosonic Rb-87 atoms in an optical lattice, we realize and explore the anyon-Hubbard model, which hosts 1D anyons and features a rich phase diagram. We implement the model using techniques from Floquet engineering, realizing the statistical phase in the form of a density-dependent Peierls phase.
Using our high-resolution imaging system, we explore both the dynamical and ground state behavior in the anyon-Hubbard model. In the first set of experiments, we probe 1D anyons via two-particle quantum walks, observing the anyonic Hanbury Brown-Twiss effect, as well as the formation of bound states without on-site interactions. Once interactions are introduced, we observe spatially asymmetric transport in contrast to the symmetric dynamics of bosons and fermions.
In the next set of experiments, we adiabatically prepare and probe ground states in the anyon-Hubbard model. First, we observe continuous fermionization in the density profile with increasing statistical phase. Then, we probe the chirality of the bound states in the anyon-Hubbard model, drawing similarities to a continuum model of 1D anyons. This work constitutes the first experimental study of the anyon-Hubbard model, and lays the foundation for exploration in the strongly correlated many-body regime.Physic
