Abstract:
Based on the non-Markovian quantum Langevin equations, we obtain
time-dependent transport coefficients for an inverted oscillator coupled
linearly in the coordinate to a thermostat. We comparatively analyze
the diffusion coefficients for harmonic and inverted oscillators and study
the role of quantum statistical effects in the passage through a parabolic
barrier.
Keywords:
open quantum system, friction coefficient, diffusion coefficient, non-Markovian dynamics.
