One-dimensional fermions beyond the Luttinger liquid paradigm

This event is part of the Biophysics/Condensed Matter Seminar Series.

Abstract: In this talk I will review recent works on dynamic correlation functions in one-dimensional systems of interacting fermions. Due to the energy and momentum conservation, the correlation functions exhibit a characteristic threshold behavior. Surprisingly, the conventional harmonic fluid (a.k.a. Luttinger liquid) framework is not sufficient for the description of the threshold singularities in the correlation functions.
