Abstract
The rate of kinetic processes hindered by a potential barrier is studied in the temperature range where quantum effects are important. Based on a generalized quantum-mechanical version of Kramer’s Brownian motion approach, a rate theory accounting for thermally activated and tunneling events is presented. The temperature dependence of the rate is studied and the crossover from the Arrhenius law valid at high temperatures to quantum rate theory valid at low temperatures is discussed. The role of memory friction caused by the dissipative coupling to the environment is emphasized.
