The exciton, an excited electron–hole pair bound by Coulomb attraction, plays a key role in
photophysics of organic molecules and drives practically important phenomena such as …

The dynamics of chaos in quantum systems has attracted much interest in connection with
the fundamental aspects of quantum mechanics. We study the chaotic dynamics of both the …

Nonclassical properties of electromagnetic radiation propagating through a non-degenerate
parametric amplifier (NDPA) are investigated. A complete quantum mechanical description …

The intermodal entanglement in a two-channel symmetric nonlinear coupler, operated with
Kerr nonlinearity was investigated using the analytical method based on the Heisenberg …

Hardy's paradox can demonstrate the conflict between quantum mechanics and local
realism. Experimental testing of Hardy's paradox has been carried out, but it involved only a …

Squeezed states of light in a three-channel nonlinear coupler with second-order nonlinearity
using the phase space method and the analytical perturbative method is reported in this …

The nonclassical properties along with the quantum phase properties have been
investigated in the case of coherent exciton–vacuum photon interaction in a semiconductor …

The significance of beamsplitter in experimental optical quantum information processing and
quantum technology is discussed with a focus on the role of a beamsplitter-type Hamiltonian …

The coherent light interacting with a direct band-gap semiconductor is modelled as two
coupled harmonic oscillators with Kerr-type nonlinearity in one of the oscillators. By …

The generation of squeezed states of light in two guided waves Kerr nonlinear coupler
(KNLC) was examined using both the analytical perturbative (AP) and the short-time …
