Math-Physics Synergy: One Mathematician's Viewpoint

Having been privilaged to work jointly with mathematical and theoretical physicists in the interdisciplinary projects SFB 237, Unordnung und grosse Fluktuationen, and currently in SFB/TR 12, Universality and symmetry in mesoscopic systems, we have experienced various sides of math-physics synergy. In the talk we will report on three projects which, in our opinion, re?ect
in di?erent ways possibilities for this synergy. These are the study of random matrix properties of disordered bosons, the symmetric space classi?cation of fermionic ensembles, which form a basis of one theory of topological insu- lators, and the analysis of degree of entanglement in quantum information theoretic settings via symplectic techniques. We will conclude the talk by indicating several basic principles which we feel are essential for interdisciplinary research.

Supersymmetric Decoupling in Cosmology

Supersymmetry is a symmetry that transforms particles of di?erent spin into each other. Some of the most prominent candidates to explain the physics above the electroweak scale are supersymmetric theories, such as the Minimal Supersymmetric Standard Model (MSSM), supersymmetric GUTs, and superstrings. These theories provide a framework to investigate  important cosmological problems  such as the origin of in?ation, dark matter or the present day accelerated expansion. In this talk we will give an introduction to the basic concepts in supergravity, which is an extension of General Relativity invariant under supersymmetry, and in particular to the construction of supergravity models with cosmological applications.

We will end the talk with a short discussion about the problem of decoupling two sectors in a supergravity model in a way that preserves supersymmetry, which is an important  ingredient in the construction of viable inflationary models derived from Superstring theory.
