Flow of S-matrix poles for elementary quantum potentials
B. Belchev, S. G. Neale, M. A. Walton
The poles of the quantum scattering matrix (S-matrix) in the complex momentum plane have been studied extensively. Bound states give rise to S-matrix poles, and other poles corresp…
On Robin boundary conditions and the Morse potential in quantum mechanics
B. Belchev, M. A. Walton
The physical origin is investigated of Robin boundary conditions for wave functions at an infinite reflecting wall. We consider both Schrödinger and phase-space quantum mechanics (…
The Morse potential and phase-space quantum mechanics
B. Belchev, M. A. Walton
We consider the time-independent Wigner functions of phase-space quantum mechanics (a.k.a. deformation quantization) for a Morse potential. First, we find them by solving the $\ast…
On Wigner functions and a damped star product in dissipative phase-space quantum mechanics
B. Belchev, M. A. Walton
Dito and Turrubiates recently introduced an interesting model of the dissipative quantum mechanics of a damped harmonic oscillator in phase space. Its key ingredient is a non-Hermi…
