Abstract
In the standard prescriptions (Albrecht in Phys Lett 56B:127, 1975; Hasse in J Math Phys 16:2005, 1975), nonlinear potentials were proposed to introduce a Hermitian potential operator into a Hamiltonian in order to consider quantized friction at the Schrödinger wave-function level. However, this route to understanding quantized friction is not unique. Thus, motivated by important sub-questions put forward by Albrecht and Hasse in the works cited above on the proper choice of parameters introduced in the proposed potentials, we investigate here the information-theoretic aspect of friction using an exact stationary solution for a two-particle interacting one-dimensional oscillator model atom. Specifically, we calculate the change in the diagonal entropy with respect to the well-documented frictionless case, and analyze its parameter-dependence.
