Entanglement Pre-thermalization in an Interaction Quench between Two Harmonic Oscillators
Tatsuhiko N. Ikeda, Takashi Mori, Eriko Kaminishi +1
Entanglement pre-thermalization (EP) is a quasi-stationary nonequilibrium state of a composite system in which each individual subsystem looks thermal but the entire system remains…
Weak eigenstate thermalization with large deviation bound
Takashi Mori
We investigate the eigenstate thermalization hypothesis (ETH) for a translationally invariant quantum spin system on the -dimensional cubic lattice under the periodic boundary c…
Classical ergodicity and quantum eigenstate thermalization: Analysis in fully connected Ising ferromagnets
Takashi Mori
We investigate the relation between the classical ergodicity and the quantum eigenstate thermalization in the fully connected Ising ferromagnets. In the case of spin-1/2, an expect…
Extensive increase of entropy in quantum quench
Takashi Mori
In the setup of isolated quantum systems, it is proved that the thermodynamic entropy and the diagonal entropy must increase extensively in any nontrivial quantum quench. The exten…
Macrostate equivalence of two general ensembles and specific relative entropies
Takashi Mori
The two criteria of ensemble equivalence, i.e. the macrostate equivalence and the measure equivalence, are investigated for a general pair of states. The macrostate equivalence imp…
