Dissipative Effect and Tunneling Time
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 app...
متن کاملQuantum vortex creep :Hall and dissipative tunneling
Within the framework of the path-integral approach we study the quantum vortex creep for the situation where both the Hall and the dissipative dynamics are simultaneously present. We calculate the relaxation rate and the crossover temperature separating the thermal activation and the quantum tunneling processes for anisotropic or multilayer superconductors. The results are compared with the ava...
متن کاملExactly solvable model of dissipative vortex tunneling
I consider the problem of vortex tunneling in a two-dimensional superconductor. The vortex dynamics is governed by the Magnus force and the Ohmic friction force. Under-barrier motion in the vicinity of the saddle point of the pinning potential leads to a model with quadratic Hamiltonian which can be analytically diagonalized. I find a non-monotonic dependence of the tunneling probability on the...
متن کاملDissipative Quantum Tunneling : Quantum Langevin Equation Approach
The quantum Langevin equation is used as the basis for a discussion of dissipative quantum tunneling. A general analysis, including strong coupling and non-markovian (memory) effects, is given for the case oftunneling through a parabolic barrier at zero temperature in the presenceof linear passive dissipation. It is shown that dissipation always decreases the tunneling rate below the barrier an...
متن کاملDissipative tunneling control by elliptically polarized fields
The tunneling dynamics of a dissipative two-level system that is strongly driven by elliptically polarized electric fields is investigated. The dissipative dynamics is governed within the noninteracting-blip-approximation for the stochastic forces by a generalized master equation ~GME!. With the focus being on viscous friction, we compare exact numerical solutions of the GME with analytical app...
