Creation of coherent superposition states in hydrogenlike ions via multiphoton resonant excitation
- Department of Quantum Electronics, Yerevan State University, 1 A. Manukian St., Yerevan 375025 (Armenia)
On the basis of the analytical solution of the Dirac equation the resonant multiphoton excitation of highly charged hydrogenlike ions in a strong high-frequency laser field is investigated. It is shown that the dynamics of the relativistic system is equivalent to two independent four-level systems (in the electrical-dipole approximation). The time evolution of the system is found using the nonperturbative resonant approach. We predict that due to multiphoton excitation by an appropriate laser pulse one can achieve various coherent superposition states in atomic or ionic systems with a high nuclear charge.
