Detecting multiple temperatures Most people have an intuitive understanding of temperature. In the context of statistical mechanics, the higher the temperature, the more a system is removed from its lowest energy state. Things become more complicated in a nonequilibrium system governed by quantum mechanics and constrained by several conserved quantities. Langen et al. showed that as many as 10 temperature-like parameters are necessary to describe the steady state of a one-dimensional gas of Rb… 
Generalized Gibbs ensemble in integrable lattice models
The generalized Gibbs ensemble (GGE) was introduced ten years ago to describe observables in isolated integrable quantum systems after equilibration. Since then, the GGE has been demonstrated to be a
Time-dependent generalized Gibbs ensembles in open quantum systems
Generalized Gibbs ensembles have been used as powerful tools to describe the steady state of integrable many-particle quantum systems after a sudden change of the Hamiltonian. Here we demonstrate
Equilibration towards generalized Gibbs ensembles in non-interacting theories
Even after almost a century, the foundations of quantum statistical mechanics are still not completely understood. In this work, we provide a precise account on these foundations for a class of
Measuring effective temperatures in a generalized Gibbs ensemble.
TLDR
It is argued that in a number of simple models these parameters can be effectively determined by using fluctuation-dissipation relationships between response and correlation functions of natural observables, quantities which are accessible in experiments.
Work and entropy production in generalised Gibbs ensembles
Recent years have seen an enormously revived interest in the study of thermodynamic notions in the quantum regime. This applies both to the study of notions of work extraction in thermal machines in
Quantum thermalization through entanglement in an isolated many-body system
TLDR
Microscopy of an evolving quantum system indicates that the full quantum state remains pure, whereas thermalization occurs on a local scale, whereas entanglement creates local entropy that validates the use of statistical physics for local observables.
Noncommutative generalized Gibbs ensemble in isolated integrable quantum systems
The generalized Gibbs ensemble (GGE), which involves multiple conserved quantities other than the Hamiltonian, has served as the statistical-mechanical description of the long-time behavior for
Microcanonical and resource-theoretic derivations of the thermal state of a quantum system with noncommuting charges
TLDR
This work defines a resource-theory model for thermodynamic exchanges of noncommuting observables and investigates the thermal state of the grand canonical ensemble, which is expected to be the equilibrium point of typical dynamics.
Noncommuting conserved charges in quantum many-body thermalization.
TLDR
This work introduces noncommuting conserved quantities from QI-theoretic thermodynamics into quantum many-body physics: atomic, molecular, and optical physics and condensed matter.
Probing non-thermal density fluctuations in the one-dimensional Bose gas
Quantum integrable models display a rich variety of non-thermal excited states with unusual properties. The most common way to probe them is by performing a quantum quench, i.e., by letting a

Thermalization and its mechanism for generic isolated quantum systems
TLDR
It is demonstrated that a generic isolated quantum many-body system does relax to a state well described by the standard statistical-mechanical prescription, and it is shown that time evolution itself plays a merely auxiliary role in relaxation, and that thermalization instead happens at the level of individual eigenstates, as first proposed by Deutsch and Srednicki.
Relaxation in a completely integrable many-body quantum system: an ab initio study of the dynamics of the highly excited states of 1D lattice hard-core bosons.
TLDR
The relaxation hypothesis is confirmed through an ab initio numerical investigation of the dynamics of hard-core bosons on a one-dimensional lattice, and a natural extension of the Gibbs ensemble to integrable systems results in a theory that is able to predict the mean values of physical observables after relaxation.

Relaxation and Prethermalization in an Isolated Quantum System
TLDR
Measurements of full quantum mechanical probability distributions of matter-wave interference are used to study the relaxation dynamics of a coherently split one-dimensional Bose gas and obtained comprehensive information about the dynamical states of the system.
Many-body localization in one dimension as a dynamical renormalization group fixed point.
TLDR
A dynamical real space renormalization group approach to describe the time evolution of a random spin-1/2 chain, or interacting fermions, initialized in a state with fixed particle positions identifies a many-body localized state of the chain as a dynamical infinite randomness fixed point, which become asymptotically exact conservation laws at the fixed point.
Constructing the generalized Gibbs ensemble after a quantum quench.
TLDR
A general construction is exhibited of the thermodynamic ensemble that has been suggested to govern this dynamics, the generalized Gibbs ensemble, and the predictions of equilibration from this ensemble are compared against the long time dynamics observed using this method.
