Charge-current generation in atomic systems induced by optical vortices
(Amer Physıcal Soc, 2012)
We envisage the possibility of producing and tuning electronic orbital currents in atoms by weak, spatially inhomogeneous laser pulses with optical vortices. As already known, when interacting with such pulses an electronic ...
The effect of dilute nitrogen on nonlinear optical properties of the InGaAsN/GaAs single quantum wells
(Sprınger, 2012)
In this study, we investigate the linear and third order nonlinear optical properties of InGaAsN/GaAs depending on nitrogen content and laser dressing parameter. As theoretical models, band anticrossing and model solid ...
A simple analytical expression for bound state energies for an attractive Gaussian confining potential
(Iop Publıshıng Ltd, 2012)
A simple analytical expression for bound state energies of an electron confined in an attractive Gaussian potential has been obtained. In order to solve Schrodinger's equation, we have used a combination of perturbation ...
Fast computations of the dielectric response of systems with spherical or axial symmetry
(Amer Physıcal Soc, 2012)
When the size of a system does not permit a quantum-mechanical treatment it is still possible to obtain an accurate description of the collective electronic excitations by using a semiclassical approximation for the ...
