Lay Summary (English)

Lead
Lay summary
Transport of current, heat or spin are among the most visible features of large quantum system. Sometimes they are characterized by a striking stability with respect to variations of external conditions, such as in topological insulators. Some transport properties appear to be insensitive not only in regard to conservative forces, but even to some forms of friction.The project is a research effort in Mathematical Physics. It aims at unraveling the mathematical structures underlying these and similar transport properties. Despite the complexity and variety of the considered systems at a fundamental level, they display - at a more abstract level - fairly universal geometrical concepts, like curvature and topological indices. Nevertheless such descriptions are often not unique. One aim is to relate some of those different geometric concepts. Another, and more extensive one, is to extend the "geometrization of transport" to open quantum system. This involves a careful and extensive study of their dynamics, which is quite different from that of the more conventional isolated systems. We intendend to develop some new views on quantum transport which are mathematically transparent and of lasting value.

Abstract

The applicant proposes a research plan in Mathematical Physics suited to make best use of the joint expertise of a new postdoc and of his own. The intended postdoc, to be employed at ETH beginning Fall 2010, is Marcello Porta, a PhD graduate from the University of Rome 1, advised by G. Gallavotti. The research to be performed is about one or several of the following topics,as further detailed in Section 2.2: (i) fluctuation theorems in non-equilibrium statistical mechanics, (ii) constructive quantum field theory,(iii) scattering in quantum field theory,(iv) topological insulators.
