Approach to ergodicity in quantum wave functions
Bruno Eckhardt, Shmuel Fishman, Jonathan Keating +3
According to theorems of Shnirelman and followers, in the semiclassical limit the quantum wavefunctions of classically ergodic systems tend to the microcanonical density on the ene…

Semiclassical form factor of matrix element fluctuations
Bruno Eckhardt, Joerg Main
We analyze within a semiclassical approximation the form factor for the fluctuations of quantum matrix elements around their classical average. We find two contributions: one is pr…
