Let a non-integrable quantum system be given, and let the strong eigenstate thermalization hypothesis (strong ETH) denote the property corresponding to Lemma 4 for the system's coa…

Let a quantum system evolve under a time-independent Hamiltonian, and let $A$ be a subsystem. Entropy thermalization means that, after long-time evolution, the entropy of $A$ agree…

A black hole horizon with its probes can be regarded as a closed quantum system, whose entropy is $S$ and inverse temperature is $\beta$. The fast-scrambler conjecture. Black hole…
