Wigner distributions for finite dimensional quantum systems: An algebraic approach
We discuss questions pertaining to the definition of ‘momentum’, ‘momentum space’, ‘phase space’ and ‘Wigner distributions’; for finite dimensional quantum systems. For such systems, where traditional concepts...

Ray space ‘Riccati’ evolution and geometric phases for N-level quantum systems
We present a simple derivation of the matrix Riccati equations governing the reduced dynamics as one descends from the group $$ \mathb...
