Abstract:It has long been appreciated that exactly solved mathematical models describing the statistical mechanics of interacting particles have played a key role in the development of formerly unrelated areas of mathematics and theoretical physics. However, over the past two decades striking experimental achievements in trapping and cooling atoms in one-dimensional optical waveguides have provided remarkable realisations of exactly solved models in the lab. In particular, the study of interacting fermions provides a unique environment to explore novel quantum many-body effects like quantum liquids, criticality, nonequlibrium thermodynamics, generalized hydro -dynamics, transport and metrology in one dimension. In this talk, I will describe some fundamental concepts of quantum integrability of the Yang-Gaudin model, i.e. the 1D delta-function interacting Fermi gas, and their relevance to recent and future experiments with this mathematical toy model.
