Generalized Thermalization in an Integrable Lattice System
, 2011 After a quench, observables in an integrable system may not relax to the standard thermal values, but can relax to the ones predicted by the generalized Gibbs ensemble (GGE) [M. Rigol et al., Phys. Rev. Lett. 98, 050405 (2007)]. The GGE has been shown to

From Interacting Particles to Equilibrium Statistical Ensembles [PDF]
, 2017 We argue that a particle language provides a conceptually simple framework for the description of anomalous equilibration in isolated quantum systems. We address this paradigm in the context of integrable models, which are those with particles that are ...

Initial state dependence of the quench dynamics in integrable quantum systems. II. Thermal states
, 2012 We study properties of isolated integrable quantum systems after a sudden quench starting from thermal states. We show that, even if the system is initially in thermal equilibrium at finite temperature, the diagonal entropy after a quench remains a ...

White Matter Abnormalities in Patients with Treatment-Resistant Genetic Generalized Epilepsies. [PDF]
, 2016 BACKGROUND Genetic generalized epilepsies (GGEs) are associated with microstructural brain abnormalities that can be evaluated with diffusion tensor imaging (DTI). Available studies on GGEs have conflicting results.

On equilibration and coarsening in the quantum O(N) model at infinite $N$
, 2013 The quantum O(N) model in the infinite $N$ limit is a paradigm for symmetry-breaking. Qualitatively, its phase diagram is an excellent guide to the equilibrium physics for more realistic values of $N$ in varying spatial dimensions ($d>1$).

Finite-size corrections vs. relaxation after a sudden quench
, 2012 We consider the time evolution after sudden quenches of global parameters in translational invariant Hamiltonians and study the time average expectation values and entanglement entropies in finite chains.

Relaxation dynamics of an exactly solvable electron-phonon model
, 2010 We address the question whether observables of an exactly solvable model of electrons coupled to (optical) phonons relax into large time stationary state values and investigate if the asymptotic expectation values can be computed using a stationary ...

Dissipation in the Generalized Gibbs Ensemble
, 2017 In this work, we show that the dissipation in a many-body system under an arbitrary non-equilibrium process is related to the R\'{e}nyi divergences between two states along the forward and reversed dynamics under very general family of initial conditions.

Quench action approach for releasing the N\'eel state into the spin-1/2 XXZ chain
, 2014 The steady state after a quantum quench from the N\'eel state to the anisotropic Heisenberg model for spin chains is investigated. Two methods that aim to describe the postquench non-thermal equilibrium, the generalized Gibbs ensemble and the quench ...

Fluctuation Theorem for Quasi-Integrable Systems
, 2018 A Fluctuation Theorem (FT), both Classical and Quantum, describes the large-deviations in the approach to equilibrium of an isolated quasi-integrable system. Two characteristics make it unusual: (i) it concerns the internal dynamics of an isolated system
