dc.descriptionJha, P. K., Eleuch, H., & Rostovtsev, Y. V. (2010). Coherent control of atomic excitation using off-resonant strong few-cycle pulses. Physical review A, 82(4), 045805.
dc.description.abstractWe study the dynamics of a two-level system driven by an off-resonance few-cycle pulse which has a phase jump φ at t = t0, in contrast to many-cycle pulses, under the nonrotating-wave approximation (NRWA). We give a closed form analytical solution for the evolution of the probability amplitude |Ca (t)| for the upper level. Using the appropriate pulse parameters like the phase jump φ, jump time t0, pulse width τ , frequency ν, and Rabi frequency 0 the population transfer after the pulse is gone can be optimized and, for the pulse considered here, an enhancement factor of 106–108 was obtained.en_US
