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. García-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…
Quantum energy teleportation in phase space quantum mechanics
M. M. Sanchez-Cordova, Jasel Berra-Montiel
In this paper, we investigate the Quantum Energy Teleportation protocol within the phase space formulation of quantum mechanics. By employing the Wigner quasi-probability distribut…
Star product representation of coherent state path integrals
Jasel Berra-Montiel
In this paper, we determine the star product representation of coherent path integrals. By employing the properties of generalized delta functions with complex arguments, the Glaub…
Coherent representation of fields and deformation quantization
Jasel Berra-Montiel, Alberto Molgado
Motivated by some well-known results in the phase space description of quantum optics and quantum information theory, we aim to describe the formalism of quantum field theory by ex…
Deformation quantization of the Pais-Uhlenbeck fourth order oscillator
Jasel Berra-Montiel, Alberto Molgado, Efraín Rojas
We analyze the quantization of the Pais-Uhlenbeck fourth order oscillator within the framework of deformation quantization. Our approach exploit the Noether symmetries of the syste…
