Previous works showed that thin layers of fatty acids and fatty acid–cholesterol mixtures behaved as optical liquid crystals, even at low incident laser power. The paper presents an experimental and computer study of laser signals, emergent from su

The nonlinear dynamics of an erbium-doped fiber laser is explained based on a simple model of the ion pairs present in heavily doped fibers. The single-mode laser dynamics is reductible to four nonlinear differential equations. Depending on the ion p

In this papcr, thin films of some fatty acids and fatty acid-cholesterol mixtures were investigated asbiological membrane simple models, in order to establish the thermal neutron irradiation influence on these systems, while in the smectic C liquid c

An essential problem of the quantum information systems is the controllability and observability of the quantum states, generally described by Lindblad's master equation with phenomenological coefficients. However, in its general form, this equation

Maxwell-Bloch equations generalized for a dense medium of two- level atoms are used to describe the dynamics of the system under the action of an ultrafast optical pulse. Starting with an uninverted system, the final population is one of the two extr
