Oral History Interview: Jeffrey Schachner (1384)
No full textIn his May 2014 interview with Troy Reeves, Jeffrey Schachner details his remembrances of his undergraduate years at the University of Wisconsin-Madison, with special reference to his activism with SDS during the Dow Riot and the Black Students? Strike of 1969. Schachner expressed his deep concern that the strike be remembered as a pivotal part of the larger civil rights movement of the 1960s, and contextualized many of the key participants in these events. This interview was conducted for inclusion into the UW-Madison Oral History Program

The “Hattusa Project”. A German-Italian Cooperation for the Three- Dimensional Documentation and Representation of an UNESCO Archaeological Site
No full textWith the establishment of the cooperation project between the University Suor Orsola Benincasa of Naples and the archaeological mission in Hattuša of the German Archaeological Institute of Istanbul, directed by Andreas Schachner, and in agreement with the Turkish Ministry of Culture and Tourism, a workgroup of the University of Naples was formed in order to carry out a 3D survey campaign concerning sections of the site of Hattusa and the entire site of azılıkaya.
These activities have been finalized at creating integrated 3D models of both the territorial context and of the monuments object of the research, through the application of diverse scanning techniques, in accordance to the different levels of detail required for each subject (topography, rocky complex, the cultural spaces therein, complex of sculptural reliefs, inscriptions accompanying the divine representations) and to virtually reproduce them for safeguard, exhibition and study purposes (with particular emphasis on the epigraphic and historic-artistic point of view) all the geometric aspects characterizing the artefacts and, in many cases, not completely visible to the naked eye today

Systematics of type IIB moduli stabilisation with odd axions
No full textModuli stabilisation in superstring compactifications on Calabi-Yau orientifolds remains a key challenge in the search for realistic string vacua. In particular, odd moduli arising from the reduction of 2-forms (B2, C2) in type IIB are largely unexplored despite their relevance for inflationary model building. This article provides novel insights into the general structure of 4D N = 1 F-term scalar potentials at higher orders in the α′ and gs expansion for arbitrary Hodge numbers. We systematically examine superpotential contributions with distinct moduli dependences which are induced by fluxes or non-perturbative effects. Initially, we prove the existence of a no-scale structure for odd moduli in the presence of (α′)3 corrections to the Kähler potential. By studying a partially SL(2, Z)-completed form of the Kähler potential, we derive the exact no-scale breaking effects at the closed string 1-loop and non-perturbative D-instanton level. These observations allow us to present rigorous expressions for the F-term scalar potential applicable to arbitrary numbers of moduli in type IIB Calabi-Yau orientifold compactifications. Finally, we compute the Hessian for odd moduli and discuss potential phenomenological implications

Systematics of the α′ expansion in F-theory
No full textExtracting reliable low-energy information from string compactifications notoriously requires a detailed understanding of the UV sensitivity of the corresponding effective field theories. Despite past efforts in computing perturbative string corrections to the tree-level action, neither a systematic approach nor a unified framework has emerged yet. We make progress in this direction, focusing on the moduli dependence of perturbative corrections to the 4D scalar potential of type IIB Calabi-Yau orientifold compactifications. We proceed by employing two strategies. First, we use two rescaling symmetries of type IIB string theory to infer the dependence of any perturbative correction on both the dilaton and the Calabi-Yau volume. Second, we use F/M-theory duality to conclude that KK reductions on elliptically-fibred Calabi-Yau fourfolds of the M-theory action at any order in the derivative expansion can only generate (α′)even corrections to the 4D scalar potential, which, moreover, all vanish for trivial fibrations. We finally give evidence that (α′)odd effects arise from integrating out KK and winding modes on the elliptic fibration and argue that the leading no-scale breaking effects at string tree-level arise from (α′)3 effects, modulo potential logarithmic corrections
