ANNUNCIO DI SEMINARIO DI FISICA MATEMATICA / MATHEMATICAL PHYSICS SEMINAR

On June 30 at 10:00 we will have a mathematical physics seminar by



Manfred Salmhofer (University of Heidelberg).

----------------------------------
Functional Integrals for Bose Ensembles

I discuss rigorously defined coherent-state functional integral representations for the partition function and correlation functions of many-boson systems, both for the canonical and the grand-canonical ensemble, and the relation of these representations to ensembles of interacting random walks. I will highlight a few essential differences between the canonical and grand-canonical ensemble, outline the proof of equivalence of different functional integral representations in the time-continuum limit, and discuss expansions for the correlation functions.
----------------------------------

Everyone interested is invited to participate. The seminar will be held remotely on Zoom. For further information and the zoom link, please contact Niels Benedikter, niels.benedikter@unimi.it.
