Phys. Rev. Lett. 46, 211–214 (1981)Influence of Dissipation on Quantum Tunneling in Macroscopic SystemsReceived 28 July 1980; published in the issue dated 26 January 1981 A quantum system which can tunnel, at T=0, out of a metastable state and whose interaction with its environment is adequately described in the classically accessible region by a phenomenological friction coefficient η, is considered. By only assuming that the environment response is linear, it is found that dissipation multiplies the tunneling probability by the factor exp[-Aη(Δq)2/ℏ], where Δq is the "distance under the barrier" and A is a numerical factor which is generally of order unity. © 1981 The American Physical Society URL:
