Using density matrix equation, we calculate analytically as well as numerically the effect of the four-wave mixing (FWM) field on electromagnetically induced tr
In this paper, the stellar velocity dispersions in the host galaxies are used to estimate the central black hole masses for a sample of elliptical galaxies. We
Nanocrystalline Prl2Fe82B6 and nanocomposite Pr8Fe87B5 ribbons have been prepared using a melt spinning technique. Recoil loops have been measured at 20, 200 an
We study the dynamics of vectorial coupled-mode solitons in one-dimensional photonic crystals with quadraticand cubic nonlinearities. Starting from Maxwell’s e
The effect of dust charge variation on the dust-acoustic solitary structures is investigated in a warm magnetized two-ion-temperature dusty plasma consisting of
We study the dynamical behaviour of the ionic inversion in a trapped ion system in running-wave lasers, and wediscuss the properties of entanglement between the
A spin-1/2 and spin-3/2 mixed Ising system in a random field is studied by the use of effective-field theory with correlations. The phase diagrams and thermal b
