Macroscopic Quantum Tunneling

A stochastic model, which demonstrated to be capable of determining dissipative effects in the microwave circuits loading superconducting devices, is found to be suitable also for analyzing near-field microwave propagation when the wave attenuation is interpreted as a dissipative effect. An alternative approach to the problem is offered by Feynman’s transition elements.

The role of Aharonov–Bohm effect in quantum tunneling is examined when a potential is defined on the S1 and has N-fold symmetry. We show that the low-lying energy levels split from the N-fold degenerate ground state oscillate with the Aharonov–Bohm phase, from which general degeneracy conditions depending on the magnetic flux is obtained. We apply these results to the spin tunneling in a spin system with N-fold rotational symmetry around a hard axis.
