Chaotic instantons in periodically perturbed double-well system

Kicked double-well system is investigated using chaotic instanton approach. Phenomenological formula for dependence of ground quasienergy splitting on value and frequency of perturbation is obtained analytically. Results of performed numerical calculations are in good agreement with phenomenological formula.

Joint work with with Viatcheslav Kuvshinov and Andrei Kuzmin.
