The decay of a metastable state of a system coupled to a heat-bath environment is studied. A functional-integral method is presented allowing for the calculation of decay rates at finite temperatures and in the presence of dissipation. The theory is

The quantum-mechanical decay of a metastable state of a system coupled to a heat bath environment is studied. A functional integral method is presented allowing for the calculation of decay rates at finite temperatures and in the presence of dissipat
The temperature dependence of the decay rate of a metastable state of a system coupled to a dissipative environment is determined. Kramers' classical theory of the rate of decay by thermal activation is extended to lower temperatures where quantum tu

The exponent and the prefactor of the decay rate of a metastable system coupled to an environment at temperature T are determined. Analytical methods for high and intermediate temperatures are combined with an accurate numerical method for low temper

The rate of decay of metastable states of Josephson systems is determined for a wide range of parameters. The temperature extends from the region where the decay is thermally activated down to very low temperatures where the system decays by macrosco
