Abstract: The Eigenstate Thermalization Hypothesis (ETH) has played a key role in recent advances in the high energy and condensed matter communities. It explains how an isolated quantum system in a far-from-equilibrium initial state can evolve to a state that is indistinguishable from thermal equilibrium, with observables relaxing to almost time-independent results that can be described using traditional statistical mechanics ensembles. In this work we probe the limits of ETH, pushing it outside its prototypical applications in several directions. We design a qutrit lattice system with conserved quasilocal charge, in which we verify a form of generalized eigenstate thermalization. We also observe signatures of thermalization in states well outside microcanonical windows of both charge and energy, which we dub `generic ETH.'

Exact Thermal Eigenstates of Nonintegrable Spin Chains at Infinite Temperature [0.0]
We write down analytically thermal eigenstates of nonintegrable spin chains. We identify Hamiltonians having the EAP state as an eigenstate and rigorously show that some of these Hamiltonians are nonintegrable. Our results offer a potential avenue for providing a provable example of the eigenstate thermalization hypothesis.

Non-Abelian eigenstate thermalization hypothesis [58.720142291102135]
The eigenstate thermalization hypothesis (ETH) explains why chaotic quantum many-body systems thermalize internally if the Hamiltonian lacks symmetries. We adapt the ETH to noncommuting charges by positing a non-Abelian ETH and invoking the approximate microcanonical subspace introduced in quantum thermodynamics.

On eigenstate thermalization in the SYK chain model [0.0]
Eigenstate thermalization hypothesis (ETH) explains how generic observables of individual isolated quantum systems in pure states can exhibit thermal behaviors. We show that for two conventional few-body operators, the ensemble-averaged theory of the SYK chain model strictly satisfies ETH conditions.

Probing eigenstate thermalization in quantum simulators via fluctuation-dissipation relations [77.34726150561087]
The eigenstate thermalization hypothesis (ETH) offers a universal mechanism for the approach to equilibrium of closed quantum many-body systems. Here, we propose a theory-independent route to probe the full ETH in quantum simulators by observing the emergence of fluctuation-dissipation relations. Our work presents a theory-independent way to characterize thermalization in quantum simulators and paves the way to quantum simulate condensed matter pump-probe experiments.
