Eigenstate thermalization
Rohit Patil, Marcos Rigol
We provide a pedagogical introduction to eigenstate thermalization. This phenomenon, which occurs in generic quantum systems, allows one to understand why thermalization takes plac…

Eigenstate thermalization for local versus translationally invariant observables
Rohit Patil, Marcos Rigol
Local observables and their translationally invariant counterparts are generally thought to provide the same predictions for experiments. While this equivalence holds for expectati…

Eigenstate thermalization in spin- systems with SU(2) symmetry
Rohit Patil, Marcos Rigol
We study the diagonal and off-diagonal matrix elements of observables in the eigenstates of the extended spin- Heisenberg chain, which exhibits the non-Abelian SU(2) s…
