Alternative linear structures for classical and quantum systems
E. Ercolessi, A. Ibort, G. Marmo +1
The possibility of deforming the (associative or Lie) product to obtain alternative descriptions for a given classical or quantum system has been considered in many papers. Here we…

Ray space Riccati evolution and geometric phases for N-level quantum systems
S. Chaturvedi, E. Ercolessi, G. Marmo +3
We present a simple derivation of the matrix Riccati equations governing the reduced dynamics as one descends from the group U(N) describing the Schroedinger evolution of an N-leve…
