Semiclassical Inequivalence of Polygonalized Billiards
Debabrata Biswas
Polygonalization of any smooth billiard boundary can be carried out in several ways. We show here that the semiclassical description depends on the polygonalization process and the…
The Arbitrary Trajectory Quantization Method
Debabrata Biswas
The arbitrary trajectory quantization method (ATQM) is a time dependent approach to quasiclassical quantization based on the approximate dual relationship that exists between the q…
Escape from noisy intermittent repellers
Debabrata Biswas, B. A. R. C, Mumbai +1
Intermittent or marginally-stable repellers are commonly associated with a power law decay in the survival fraction. We show here that the presence of weak additive noise alters th…
Closed almost-periodic orbits in semiclassical quantization of generic polygons
Debabrata Biswas
Periodic orbits are the central ingredients of modern semiclassical theories and corrections to these are generally non-classical in origin. We show here that for the class of gene…
Distribution of Husimi Zeroes in Polygonal Billiards
Debabrata Biswas, Sudeshna Sinha
The zeroes of the Husimi function provide a minimal description of individual quantum eigenstates and their distribution is of considerable interest. We provide here a numerical st…
Periodic Orbits and Spectral Statistics of Pseudointegrable Billiards
Debabrata Biswas
We demonstrate for a generic pseudointegrable billiard that the number of periodic orbit families with length less than increases as , where …
