Chaotic resonance modes in optical microcavities — •Florian Lorenz and Roland Ketzmerick — TU Dresden, Institut für Theoretische Physik, Dresden, Germany

Following a recently proposed conjecture, we show that resonance modes in dielectric cavities are a product of a conditionally invariant measure from classical dynamics and universal fluctuations [1]. The first factor describes the average of modes with similar lifetime and has a multifractal structure which we resolve on very fine scales. It is approximately described by conditionally invariant measures from classical dynamics [1]. However, increasing the openness of a dielectric cavity (i.e. by investigating TE modes or a small refractive index) is a challenge to the construction of appropriate classical measures.
