A semiclassical derivation of Einstein's rate equations for light-matter interaction
G. J. de Valcarcel, Eugenio Roldan
Einstein's rate equations are derived from the semiclassical Bloch equations describing the interaction of a classical broadband light field with a two--level system.
Two-Photon Absorption
I. Perez-Arjona, G. J. de Valcarcel, Eugenio Roldan
Two-photon absorption is theoretically analyzed within the semiclassical formalism of radiation-matter interaction. We consider an ensemble of inhomogeneously broadened three-level…
Complex Ginzburg-Landau equation for self-oscillatory systems under amplitude modulated forcing in a 1:1 resonance
German J. de Valcarcel
The dynamics of self-oscillatory extended systems, resonantly forced at a frequency close to that of the natural oscillations (1:1 resonance), is shown to be universally described…
Dark-ring cavity solitons in lasers with bichromatic injected signal
German J. de Valcarcel, Kestutis Staliunas
We show theoretically that broad area lasers driven by a nearly resonant bichromatic field may support dark-ring cavity solitons as well as domain walls and labyrinthine patterns.
Faraday patterns in Bose-Einstein condensates. Amplitude equation for rolls in the parametrically driven, damped Gross-Pitaevskii equation
German J. de Valcarcel
The parametrically driven, damped Gross-Pitaevskii equation, which models Bose-Einstein condensates in which the interatomic s-wave scattering length is modulated in time, is shown…
