Quantum quench in the Luttinger model with finite temperature initial state
Ádám Bácsi, Balázs Dóra
We study the non-equilibrium dynamics of the Luttinger model after a quantum quench, when the initial state is a finite temperature thermal equilibrium state. The diagonal elements…

Generalized Gibbs ensemble and work statistics of a quenched Luttinger liquid
Balázs Dóra, Ádám Bácsi, Gergely Zaránd
We analyze the probability distribution function (PDF) of work done on a Luttinger liquid for an arbitrary finite duration interaction quench and show that it can be described in t…

Mean-field quantum phase transition in graphene and in general gapless systems
Ádám Bácsi, Attila Virosztek, László Borda +1
We study the quantum critical properties of antiferromagnetism in graphene at T=0 within mean-field (MF) theory. The resulting exponents differ from the conventional MF exponents,…
