Random walks in finite Abelian groups with Birkhoff subpolytopes of doubly stochastic matrices and their physical implementation
A. Vourdas
Random walks in a finite Abelian group are studied. They use Markov chains with doubly stochastic transition matrices, in a Birkhoff subpolytope associated with t…
Independence and totalness of subspaces in phase space methods
A. Vourdas
The concepts of independence and totalness of subspaces are introduced in the context of quasi-probability distributions in phase space, for quantum systems with finite-dimensional…
Renormalization of total sets of states into generalized bases with a resolution of the identity
A. Vourdas
A total set of states for which we have no resolution of the identity (a `pre-basis'), is considered in a finite dimensional Hilbert space. A dressing formalism renormalizes them i…
Complementarity and phases in SU(3)
H. de Guise, A. Vourdas, L. L. Sanchez-Soto
Phase operators and phase states are introduced for irreducible representations of the Lie algebra su(3) using a polar decomposition of ladder operators. In contradistinction with…
Harmonic analysis on a galois field and its subfields
A. Vourdas
Complex functions where belongs to a Galois field , are considered. Fourier transforms, displacements in the phase space an…
