Logarithmic singularity in a dynamical quantum phase transition for free fermions
Yasser Bezzaz, Dimitri M. Gangardt, Pavel L. Krapivsky +3
We study the Loschmidt echo in a system of N non-interacting spinless lattice fermions released from a double-domain-wall initial state. In the large-N limit, the return probabilit…

Rapidity distribution within the defocusing non-linear Schrödinger equation model
Yasser Bezzaz, Léa Dubois, Isabelle Bouchoule
We consider the classical field integrable system whose evolution equation is the nonlinear Schrödinger equation with defocusing non-linearities, which is the classical limit of th…
