Evolving momentum-projected densities in billiards with quantum states
Debabrata Biswas
The classical Liouville density on the constant energy surface reveals a number of interesting features when the initial density has no directional preference. It has been shown (P…

Classical projected phase space density of billiards and its relation to the quantum Neumann spectrum
Debabrata Biswas
A comparison of classical and quantum evolution usually involves a quasi-probability distribution as a quantum analogue of the classical phase space distribution. In an alternate a…

Measuring billiard eigenfunctions with arbitrary trajectories
Debabrata Biswas
We propose a method of measuring approximate quantum eigenfunctions in polygonalized billiard geometries, based on a quasiclassical evolution operator having a (smoothened) Perron-…
