Eigenstate entanglement between quantum chaotic subsystems: universal transitions and power laws in the entanglement spectrum
Steven Tomsovic, Arul Lakshminarayan, Shashi C. L. Srivastava +1
We derive universal entanglement entropy and Schmidt eigenvalue behaviors for the eigenstates of two quantum chaotic systems coupled with a weak interaction. The progression from a…

Partial Weyl Law for Billiards
Arnd Bäcker, Roland Ketzmerick, Steffen Löck +1
For two-dimensional quantum billiards we derive the partial Weyl law, i.e. the average density of states, for a subset of eigenstates concentrating on an invariant region of ph…
