Chaotic instantons and ground quasienergy levels in kicked double-well system

Vadzim Piatrou, Kuvshinov, Andrei Kuzmin

Ground quasienergy levels in the kicked double-well system are investigated both analytically and numerically. The splitting between two lowest levels is described using resonances overlap criterion in the framework of chaotic instanton approach. Results of numerical calculations of quasienergy spectrum are in good agreement with derived phenomenological formula.
