Semiclassical structure of resonance states in chaotic scatteringRoland Ketzmerick, •Florian Lorenz, and Jan Robert Schmidt — TU Dresden, Institute of Theoretical Physics, Dresden, Germany

We introduce a classical multifractal measure that describes resonance states with decay rate γ in the semiclassical limit. This measure (i) maximizes an entropy-like quantity and (ii) is conditionally invariant with the same decay rate γ. It is derived from a local random vector model and replaces previous approximate approaches. This supports the recently proposed factorization conjecture, that resonance states are a product of a classical measure and universal fluctuations [1]. These results are numerically demonstrated for optical microcavities.

Keywords: chaotic scattering; resonance states; semiclassical limit
