A fs time-resolved selective control of multilevel systems using superposition of two identical, frequency-chirped fields is proposed and demonstrated. By adjusting the delay between the pulses, a selected transition of the Rb doublet was brought into the "holes" of the interference pattern and remained nonexcited, thus allowing to manipulate another(More)
We discuss the problem of creating coherence in an optically driven quantum system in conditions where decoherence is caused by the laser field itself, due to coupling of the system to a rapidly decaying state or continuum. It is shown that by applying an additional laser field between this state and a bound state the relaxation channel can be suppressed as(More)
Neurotensin (NT) is a neuropeptide that acts as a neurotransmitter and neuromodulator in the central nervous system. Several studies suggest a therapeutic role for NT analogs in nicotine and other psychostimulant addictions. We studied the effects of the nonselective NT receptor agonist NT69L, which has equal affinity for the two major NT receptors, NTS1(More)
