Phase space methods in finite quantum systems.
Quantum systems with finite Hilbert space where position x and momentum p take values in Z(d) (integers modulo d) are considered. Symplectic tranformations S(2¿,Z(p)) in ¿-partite finite quantum systems are studied and constructed explicitly. Examples of applying such simple method is given for the …

Phase space methods for the analysis and design of discontinuous systems.
The phase space theory and its application to the analysis and design of discontinuous systems hrs been discussed for both linear and saturated systems with step and ramp inputs. The general approach is to analyze the futures of the trajectories in error space, and design various control computers …

Simulation, characterisation and control of open quantum systems dynamics
… shows flaws and inconsistencies. We thus use phase-space methods to assess the role of initial correlations shared by the two parties of a bipartite harmonic system in the entropy production rate, including non-Markovian effects. Furthermore, we show that certain interactions enable to redraw …

Bi-fractional transforms in phase space
… Both operators are important operators in phase space and the trace of both with respect to the density operator gives the Wigner functions (displaced parity operator) and Weyl functions (displacement operator). The generalisation of the parity-displacement operator relationship considered …
