Chaotic instantons and enhancement of tunneling in kicked double-well system with time-reversal symmetry
Abstract:
Kicked double-well system is investigated both analytically and numerically. Formula for ground quasienergy splitting is
obtained using effective model in the framework of chaotic instanton approach. Results of numerical calculations for the ground
quasienergy splitting dependence on both the perturbation strength and frequency are in good agreement with the derived analytical
formula. Thus providing a support for the further development of chaotic instanton approach to tunneling in quantum systems with mixed
classical dynamics.
