Continuous phase-space methods on discrete phase spaces
We show that discrete quasiprobability distributions defined via the discrete Heisenberg-Weyl group can be obtained as discretizations of the continuous SU(N) quasiprobability distributions. This is done by identifying the phase-point operators with the continuous quantisation kernels evaluated at special points of the phase space. As an application we discuss the positive-P function and show t...
متن کاملUnitary Evolution on a Discrete Phase Space
We construct unitary evolution operators on a phase space with power of two discretization. These operators realize the metaplectic representation of the modular group SL(2,Z2n). It acts in a natural way on the coordinates of the non-commutative 2-torus, T2n and thus is relevant for noncommutative field theories as well as theories of quantum space-time. The class of operators may also be usefu...
متن کاملPhase-Space Methods for Fermions
Phase-space representations first arose from the attempt to describe quantum mechanics in terms of distributions over classical variables [1]. For example, Wigner introduced a function of phase-space variables W(x, p) that would classically correspond to a joint-probability distribution: an integration over x gives the marginal distribution for p and vice-versa. However in quantum mechanics, su...
متن کاملPhase Space Observables and Isotypic Spaces
We give necessary and sufficient conditions for the set of Neumark projections of a countable set of phase space observable to constitute a resolution of the identity, and we give a criteria for a phase space observable to be informationally complete. The results will be applied to the phase space observables arising from an irreducible representation of the Heisenberg group.
متن کاملEntropy production in continuous phase space systems
We propose an alternative method to compute the environmental entropy production of a classical underdamped nonequilibrium system, not necessarily in detailed balance, in a continuous phase space. It is based on the idea that the Hamiltonian orbits of the corresponding isolated system can be regarded as microstates and that entropy is generated in the environment whenever the system moves from ...
