Abstract

The quantum Langevin equation has been studied for dissipative system using the approach of Ford et al. Here, we have considered the inverted harmonic oscillator potential and calculated the effect of dissipation on tunneling time, group delay, and the self‐interference term. A critical value of the friction coefficient has been determined for which the self‐interference term vanishes. This approach sheds new light on understanding the ion transport at nanoscale.
