Generalized bipolariton model. Propagation of a ultrashort laser pulse through a thin semiconductor film in the conditions of two-photon generation of biexcitons

BELOUSSOV, Igor (Tehnica UTM, 2013)

A generalized bipolariton model is proposed. Bipolaritons is formed from virtual excitons of four kinds. There exists both attractive and repulsive interaction between these excitons, though only excitons of a specific ...
Nonlinear Transmission of Two Successive Ultrashort Laser Pulses by a Thin Semiconductor Film under Two-Photon Generation of Biexcitons.Giant Oscillator Strength Model

BELOUSSOV, Igor; KHSDZHI, Peter; SHEMYAKOVA, Tatiana; RUSU, Spiridon (Technical University of Moldova, 2011)

The possibility was investigated to compress and to split laser pulses at their nonlinear optical transmission through semiconductor films.
Ultrafast Optomagnetic Bistable Effects in Magnetically–Ordered Dielectrics Cylindrical Nanoparticles

BARANOV, Sergei; DOBYNDE, Igor (Technical University of Moldova, 2017)

We present results of a study of the magnetization orientation in magnetically–ordered dielectrics cylindrical nanoparticles. We derive the hysteresis dependence of the equilibrium magnetization orientation X on the external ...
