Journal ArticleDOI
Correlations after quantum quenches in the XXZ Spin Chain: Failure of the generalized Gibbs ensemble
TL;DR: The GGE cannot give a complete description even of local observables, while the quench-action formalism correctly captures the steady state in this case.
Journal ArticleDOI
Real-time confinement following a quantum quench to a non-integrable model
TL;DR: In this paper, the authors show that confinement has dramatic consequences for the non-equilibrium dynamics following a quantum quench and that these effects could be exploited as a quantitative probe of confinement.
Journal ArticleDOI
Form factors in finite volume II: Disconnected terms and finite temperature correlators
Balázs Pozsgay,Gábor Takács +1 more
TL;DR: In this article, the authors considered form factors of integrable quantum field theories in finite volume, and extended their investigation to matrix elements with disconnected pieces, and gave a new method for generating a low temperature expansion, which they test for the one point function up to third order.
Journal ArticleDOI
Form factors in finite volume I: Form factor bootstrap and truncated conformal space
Balázs Pozsgay,Gábor Takács +1 more
TL;DR: In this article, the volume dependence of matrix elements of local fields to all orders in inverse powers of the volume (i.e., only neglecting contributions that decay exponentially with volume) is described.
Journal ArticleDOI
Non-linear integral equation and finite volume spectrum of sine-Gordon theory
TL;DR: In this paper, the authors examined the connection between the nonlinear integral equation derived from light-cone lattice and sine-Gordon quantum field theory, considered as a perturbed c = 1 conformal field theory.
