Аннотация:
By taking advantage of Wang’s results on the scalar product of four eigenfunctions of the 1D harmonic oscillator, we explicitly calculate the trace of the Birman–Schwinger operator of the one-dimensional harmonic oscillator perturbed by a Gaussian potential, showing that it can be written as a ratio of Gamma functions.
Ключевые слова:
Gaussian potential, Birman-Schwinger operator, trace class operator, harmonic oscillator.
