Universal Features of the Excitation Spectrum in Generalized Gibbs Distribution Ensemble
, 2012 It is shown that excitation spectra of Generalized Gibbs Ensembles (GGE) of one-dimensional integrable models with isotopic symmetry contain universal features insensitive to details of the distribution.

, 2016 We give a pedagogical introduction to the methodology of the Quench Action, which is an effective representation for the calculation of time-dependent expectation values of physical operators following a generic out-of-equilibrium state preparation ...

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 ($d>1$).

From quantum chaos and eigenstate thermalization to statistical mechanics and thermodynamics [PDF]
, 2016 This review gives a pedagogical introduction to the eigenstate thermalization hypothesis (ETH), its basis, and its implications to statistical mechanics and thermodynamics. In the first part, ETH is introduced as a natural extension of ideas from quantum

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 ...

Quantum Quenches in the Luttinger model and its close relatives
, 2016 A number of results on quantum quenches in the Luttinger and related models are surveyed with emphasis on post-quench correlations. For the Luttinger model and initial gaussian states, we discuss both sudden and smooth quenches of the interaction and the

Quantum quenches and thermalization on scale-free graphs
, 2014 We show that after a quantum quench of the parameter controlling the number of particles in a Fermi-Hubbard model on scale free graphs, the distribution of energy modes follows a power law dependent on the quenched parameter and the connectivity of the ...

Towards a Generalized Hydrodynamics description of R\'enyi entropies in integrable systems
, 2019 We investigate the steady-state R\'enyi entanglement entropies after a quench from a piecewise homogeneous initial state in integrable models. In the quench protocol two macroscopically different chains (leads) are joined together at the initial time ...

Dynamical formation and manipulation of Majorana fermions in driven quantum wires
, 2012 Controlling the dynamics of Majorana fermions (MF) subject to time-varying driving fields is of fundamental importance for the practical realization of topological quantum computing.
