The Schrödinger equation in phase space is used to calculate the Wigner function for
oscillator systems. The first is two oscillators including dissipative effects. In this case, the …

Using elements of symmetry, as gauge invariance, several aspects of a Schrödinger
equation represented in phase space are introduced and analyzed under physical basis …

Exploring the concept of the extended Galilei group G. Representations for field theories in a
symplectic manifold have been derived in association with the method of the Wigner …

We use the scalar field constructed in phase space to analyze the analogous Stefan‐
Boltzmann law and Casimir effect, both of them at finite temperature. The temperature is …

Using elements of symmetry, as gauge invariance, many aspects of a Schrödinger equation
in phase space are analyzed. The number (Fock space) representation is constructed in …

In this paper, the interaction of a scalar field and the electromagnetic field in phase space is
analyzed. The scattering process is calculated up to first order in the Planck constant which …

Neste trabalho, utilizamos uma representação da mecânica quântica simplética para
estudar teorias de calibre abeliano e não abeliano, bem como soluções da equação de …

O formalismo da mecânica quântica simplética é utilizado para a análise de sistemas
dissipativos. Para isso, previamente, foi feita uma revisão bibliográfica do formalismo de …

Abstract The Seiberg-Witten formalism has been realized as an electrodynamics in phase
space (associated to the Dirac equation written in phase space) and this fact is explored …
