Analytical study of four-wave mixing with large atomic coherence
E. A. Korsunsky, T. Halfmann, J. P. Marangos +1
Four-wave mixing in resonant atomic vapors based on maximum coherence induced by Stark-chirped rapid adiabatic passage (SCRAP) is investigated theoretically. We show the advantages…
Coherent properties of a tripod system coupled via a continuum
R. G. Unanyan, N. V. Vitanov, B. W. Shore +1
We present results from a study of the coherence properties of a system involving three discrete states coupled to each other by two-photon processes via a common continuum. This t…
Measuring a coherent superposition
N. V. Vitanov, B. W. Shore, R. G. Unanyan +1
We propose a simple method for measuring the populations and the relative phase in a coherent superposition of two atomic states. The method is based on coupling the two states to…
Coherent population transfer beyond the adiabatic limit: generalized matched pulses and higher-order trapping states
M. Fleischhauer, R. Unanyan, B. W. Shore +1
We show that the physical mechanism of population transfer in a 3-level system with a closed loop of coherent couplings (loop-STIRAP) is not equivalent to an adiabatic rotation of…
