DESCRIPTION:Speaker: Antoine Gloria\nhosted by Julian Fischer\nAbstract: In
this talk I'll present a statistical model of polymer-chain networks base
d and shall study its limit in the regime of small chain-size. In a first
part I will consider the associated free energy and prove a large-deviatio
n principle with a rate-function given by the free energy of a continuum m
odel (that takes the form of the integral of a quasiconvex energy density)
. In a second part\, assuming that the Hamiltonian is independent of the t
emperature I'll establish the convergence of the rate-function to the (cor
responding) Gamma-limit in the regime of small temperature. I will conclud
e with an application to polymer-physics\, for which the "coarse-grained"
Hamiltonian depends itself on temperature\, and shall consider a diagonal
regime.This is based on a joint work with Marco Cicalese (Munich) and Matt
hias Ruf (Brussels).
