- Abstract: Eigenstate thermalization hypothesis (ETH) is discussed. We show that one
common formulation of ETH does not necessarily imply thermalization of an
observable of isolated many body quantum system. To get thermalization one has
to postulate the canonical or microcanonical distribution in the ETH-ansatz.
More generally, any other average can be postulated in the generalized
ETH-ansatz which leads to a corresponding equilibration condition.

Eigenstate Thermalization Hypothesis (ETH) has played a key role in recent advances in high energy and condensed matter communities.
We design a qutrit lattice system with conserved quasilocal charge, in which we verify a form of generalized eigenstate thermalization.
We also observe prototypical signatures of thermalization in states well outside microcanonical windows of both charge and energy, which we dub generic ETH'
