Phys. Rev. Lett. 93, 164102 (2004) [4 pages]Quasiscarred Resonances in a Spiral-Shaped MicrocavityReceived 25 February 2004; published 15 October 2004 We study resonance patterns of a spiral-shaped dielectric microcavity with chaotic ray dynamics. Many resonance patterns of this microcavity, with refractive indices n=2 and 3, exhibit strong localization of simple geometric shape, and we call them quasiscarred resonances in the sense that there is, unlike conventional scarring, no underlying periodic orbits. It is shown that the formation of a quasiscarred pattern can be understood in terms of ray dynamical probability distributions and wave properties like uncertainty and interference. © 2004 The American Physical Society URL:
