Is the Moyal equation for the Wigner function a quantum analogue of the Liouville equation?
E. E. Perepelkin, B. I. Sadovnikov, N. G. Inozemtseva +2
The Moyal equation describes the evolution of the Wigner function of a quantum system in the phase space. The right-hand side of the equation contains an infinite series with coeff…

Exact time-dependent solution of the Schrödinger equation, its generalization to the phase space and relation to the Gibbs distribution
E. E. Perepelkin, B. I. Sadovnikov, N. G. Inozemtseva +1
Using the simplest but fundamental example, the problem of the infinite potential well, this paper makes an ideological attempt (supported by rigorous mathematical proofs) to appro…
