The Effect of Uniform and Non-uniform Electron Density Models for Determining Shock Speed of a Type II Solar Radio Burst
D P S Nilagarathne, J Adassuriya, H O Wijewardane
Solar flare is one of the most important solar activities which emit all electromagnetic waves in gigantic burst. The radio emission can be used to determine the physical propertie…
Real-time electron dynamics with exact-exchange time-dependent density-functional theory
H. O. Wijewardane, C. A. Ullrich
The exact exchange potential in time-dependent density-functional theory is defined as an orbital functional through the time-dependent optimized effective potential (TDOEP) method…
Time-dependent Kohn-Sham theory with memory
H. O. Wijewardane, C. A. Ullrich
In time-dependent density-functional theory, exchange and correlation (xc) beyond the adiabatic local density approximation can be described in terms of viscoelastic stresses in th…
Coherent control of intersubband optical bistability in quantum wells
H. O. Wijewardane, C. A. Ullrich
We present a study of the nonlinear intersubband (ISB) response of conduction electrons in a GaAs/AlGaAs quantum well to strong THz radiation, using a density-matrix approach combi…
