Spectral statistics of a pseudo-integrable map

Date: 
Tuesday 3rd April 2007 - 11:30 to 12:30
Venue: 
INI Seminar Room 1
Abstract: 

Different curious spectral properties of a quantum interval exchange map are discussed. In particular, it is demonstrated that when the matrix dimension obeys a certain congruence property the spectral statistics of the map coincides with the semi-Poisson statistics with integer and half integer level repulsion. Special attention is given to the general case where the spectral statistics is calculated by the transfer matrix approach.
