Quantum Chaos in Deformed Microcavities

Abstract

One of the behaviours to reach studying the quantum states is to consider them at the boundary of clasical mechanics whereas the applicability of clasical mechanics theory. Quantum chaos arising from semiclassical models and the classical limit of a quantum description may lead to a mechanical system with chaotic dynamics. We propose the principle to build a deformed microcavity for reseach quantum properties in chaos medium to elucidate the interplay between wave and particle natures of light. We have been used the deformed microcavity as a efficiency tool to study that chaos medium. We have developed a chechnique for realizing a two dimensional quadupolar microcavity with its deformation variable from 0% to 20 % continuosly using a liquid jet ejected from concircular orifice. With this technique, we investigated the far field evolution depending on deformation parameter from regularity to chaos.
