Chaotic behavior in lemon-shaped billiards with elliptical and hyperbolic boundary arcs

Chaotic properties of a new family , ellipse hyperbola billiards (EHB) of lemon-shaped two-dimensional billiards, interpolating between the square and the circle, whose boundaries consist of hyperbolic, parabolic or elliptical segments, depending on the shape parameter, are investigated classically and quantally.Classical chaotic fractionis were calculated and compared with the quantal level density fluctuation measures obtained by fitting the calculated level spacing sequences with the Brody, Berry-Robnik and Berry-Robnik-Brody distributions.
