Abstract: Generalized thermalization is a process that occurs in integrable systems in which unitary dynamics, e.g., following a quantum quench, results in states in which observables after equilibration are described by generalized Gibbs ensembles (GGEs). Here we discuss an emergent eigenstate construction that allows one to built emergent local Hamiltonians of which one eigenstate captures the entire generalized thermalization process following a global quantum quench. Specifically, we study the emergent eigenstate that describes the quantum dynamics of hard-core bosons in one dimension (1D) for which the initial state is a density wave and they evolve under a homogeneous Hamiltonian.

We study the ensemble of pure states supported on a small subsystem of a few modes. We find that the induced ensemble attains a universal form, independent of the choice of measurement basis.

Open-system eigenstate thermalization in a noninteracting integrable model [0.0]
We argue that even in fully integrable models, the system observables exhibit thermalization when the system-bath setup is in a typical eigenstate of its Hamiltonian. Our findings suggest that chaos and nonintegrability are not the sole drivers of thermalization.

Thermal equilibrium in Gaussian dynamical semigroups [77.34726150561087]
We characterize all Gaussian dynamical semigroups in continuous variables quantum systems of n-bosonic modes which have a thermal Gibbs state as a stationary solution. We also show that Alicki's quantum detailed-balance condition, based on a Gelfand-Naimark-Segal inner product, allows the determination of the temperature dependence of the diffusion and dissipation matrices.

Dynamical purification and the emergence of quantum state designs from the projected ensemble [0.0]
Quantum thermalization in a many-body system is defined by the approach of local subsystems towards a universal form. Projected ensemble can mimic the behavior of a maximally entropic, uniformly random ensemble. We show that absence of dynamical purification in the space-time dual dynamics yields exact state-designs for all moments $k$ at the same time.

We find that the breakdown of the quantum-classical correspondence of particle motion, via dramatically changing the spatial structure of many-body wavefunction, leads to profound changes of the entanglement structure.
