Perturbative evolution of far off - resonance driven two - level systems : Coherent population trapping , localization , and harmonic generation
The time evolution of driven two-level systems in the far off-resonance regime is studied analytically. We obtain a general first-order perturbative expression for the time-dependent density operator which is applicable regardless of the coupling strength value. In the strong field regime, our perturbative expansion remains valid even when the far off-resonance condition is not fulfilled. We fi...
متن کاملTwo-time intensity correlation in a driven three-level system.
We examine the various two-time fluorescence intensity correlations emitted by a driven three-level atom in a cascade configuration. For a strongly driven atom, the two intensity autocorrelation functions, one from the upper transition, the other from the lower transition, exhibit different behaviors. In addition to the an oscillation similar to the two-level intensity correlation we find an ad...
متن کاملConverging Perturbative Solutions of the Schrr Odinger Equation for a Two-level System with a Hamiltonian Depending Periodically on Time
We study the Schrr odinger equation of a class of two-level systems under the action of a periodic time-dependent external eld in the situation where the energy diierence 2 between the free energy levels is suuciently small with respect to the strength of the external interaction. Under suitable conditions we show that this equation has a solution in terms of converging power series expansions ...
متن کاملConverging Perturbative Solutions of the Schrödinger Equation for a Two-Level System with a Hamiltonian Depending Periodically on Time
We study the Schrödinger equation of a class of two-level systems under the action of a periodic time-dependent external field in the situation where the energy difference 2ǫ between the free energy levels is sufficiently small with respect to the strength of the external interaction. Under suitable conditions we show that this equation has a solution in terms of converging power series expansi...
متن کاملDeriving the Exact Cost Function for a Two-Level Inventory System with Information Sharing
In this paper we consider a two-level inventory system with one warehouse and one retailer with information exchange. Transportation times are constant and retailer faces independent Poisson demand. The retailer applies continuous review (R,Q)-policy. The supplier starts with m initial batches (of size Q), and places an order to an outside source immediately after the retailer’s inventory posit...
