Control of quasiparticle self-fluctuations in a CuCl crystal

ROTARU, A. KH; TRONCHU, V. Z. (Springer Nature Switzerland, 1999)

A theory is developed for regular and chaotic self fluctuations in crystal CuCl for a ring resonator geometry. A system of nonlinear differential equations is derived for the dynamic evolution of coherent excitons, photons, ...
Nonlinear propagation of light in semiconductors in the presence of two-photon excitation of biexcitons

ROTARU, A. Kh.; TRONCHU, V. Z. (Springer Nature Switzerland, 1998)

The steady-and nonsteady-state passage of light through a ring resonator in the presence of two-photon excitation of biexcitons from the ground state of the crystal is studied. The values of the parameters for which ...
Nonlinear time-independent and time-dependent propagation of light in direct-gap semiconductors with paired excitons bound into biexcitons

ROTARU, A. Kh.; TRONCHU, V. Z. (Springer Nature Switzerland, 1997)

We study a new class of nonlinear cooperative phenomena that occur when light propagates in direct-gap semiconductors. The nonlinearity here is due to a process, first discussed by A. L. Ivanov, L. V. Keldysh, and V. V. ...
