Star product for qubit states in phase space and star exponentials
Jasel Berra-Montiel, Alberto Molgado, Mar Sánchez-Córdova
In this paper, we formulate the phase space description of qubit systems using coadjoint orbits of and the Stratonovich-Weyl correspondence, yielding a deformation quantiza…
Star-exponential for Fermi systems and the Feynman-Kac formula
J. Berra-Montiel, H. GarcÃa-Compeán, A. Kafuri +1
Inspired by the formalism that relates the star-exponential with the quantum propagator for bosonic systems, in this work we introduce the analogous extension for the fermionic cas…
The Jaynes-Cummings model in Phase Space Quantum Mechanics
Mar Sanchez-Cordova, Jasel Berra-Montiel, Alberto Molgado
In this paper, we address the phase space formulation of the Jaynes-Cummings model through the explicit construction of the full Wigner function for a hybrid bipartite quantum syst…
Star exponentials and Wigner functions for time-dependent harmonic oscillators
Jasel Berra-Montiel, Daniel Contreras-Bear, Alberto Molgado +1
In this paper, we address the Wigner distribution and the star exponential function for a time-dependent harmonic oscillator for which the mass and the frequency terms are consider…
