Eigenstate entanglement entropy in the integrable spin-1/2 XYZ model
R. Świętek, M. Kliczkowski, Lev Vidmar, Marcos Rigol
Izvirni znanstveni članek
Oznake: statistična fizika;statistical physics;
We study the average and the standard deviation of the entanglement entropy of highly excited eigenstates of the integrable interacting spin-$\frac{1}{2} XYZ$ chain away from and at special lines with $U(1)$ symmetry and supersymmetry. We universally find that the average eigenstate entanglement e ...

Eigenstate thermalization has been numerically shown to occur for few-body observables in a wide range of nonintegrable models. For intensive sums of few-body observables, a weaker version of eigenstate thermalization known as weak eigenstate thermalization has been proved to occur in general. Here, ...
