Two driven coupled qubits in a time varying magnetic field: exact and approximate solutions
E. I. Lashin, Gehad Sadiek, M. Sebaweh Abdullah +1
We study the dynamics of a two-qubit system coupled through time dependent anisotropic Heisenberg interaction in presence of a time varying non-uniform external magnetic fiel…
Evolution of Fock states in three mixed harmonic oscillators: quantum statistics
Faisal A. A. El-Orany, J. Perina, M. Sebawe Abdalla
In this communication we investigate the quantum statistics of three harmonic oscillators mutually interacting with each other considering the modes are initially in Fock states. A…
Evolution of cat states in a dissipative parametric amplifier: decoherence and entanglement
Faisal A. A. El-Orany, J. Perina, V. Perinova +1
The evolution of the Schrödinger-cat states in a dissipative parametric amplifier is examined. The main tool in the analysis is the normally ordered characteristic function. Squeez…
Quantum statistics and dynamics of nonlinear couplers with nonlinear exchange
M. Sebawe Abdalla, Faisal A. A. El-Orany, J. Perina
In this paper we derive the quantum statistical and dynamical properties of nonlinear optical couplers composed of two nonlinear waveguides operating by the second subharmonic gene…
SU(2)- and SU(1,1)-squeezing of interacting radiation modes
M. Sebawe Abdalla, Faisal A. A. El-Orany, J. Perina
In this communication we discuss SU(1,1)- and SU(2)-squeezing of an interacting system of radiation modes in a quadratic medium in the framework of Lie algebra. We show that regard…
Generation of squeezed light in a nonlinear asymmetric directional coupler
Faisal A. A. El-Orany, J. Perina, M. Sebawe Abdalla
We show that a nonlinear asymmetric directional coupler composed of a linear waveguide and a nonlinear waveguide operating by nondegenerate parametric amplification is an effective…
