The theory of Bloch electron dynamics for carriers in homogeneous electric and magnetic fields of arbitrary time dependence is developed in the framework of the Liouville equation. The Wigner distribution function (WDF) is determined from the single

The fundamental quantum dynamics of two interacting oscillator systems are studied in two different scenarios. In one case, both oscillators are assumed to be linear, whereas in the second case, one oscillator is linear and the other is a non-linear,

The influence of local inhomogeneities on the electric field dependent properties of Bloch electrons is studied. The homogeneous electric field is described through the use of the vector potential, and the instantaneous Wannier functions of the homog

This paper discusses the concept of enhancing semiconductor laser performance through tailoring of scattering rates of confined polar-optical phonons. Studies of optically pumped intersubband scattering in coupled quantum-well lasers have demonstrate

In his 1959 address,'There is Plenty of Room at the Bottom,'Richard P. Feynman speculated about manipulating materials atom by atom and challenged the technical community'to find ways of manipulating and controlling things on a small scale.'This visi

The theory of Bloch electron dynamics in spatially homogeneous electric fields of arbitrary strength and time dependence is presented. In the formalism, the electric field is described through the use of the vector potential, and the instantaneous ei

Intersubband relaxation due to electron interactions with the localized phonon modes plays an important role for population inversion in quantum well laser structures designed for intersubband lasers operating at mid-infrared to submillimeter wavelen

Theoretical determination of exact-exchange-mixing parameter employing the ionization energy theorem
Publikováno v:
International Journal of Quantum Chemistry. 69:255-264
The value of Becke's exact-exchange-mixing parameter is determined by purely theoretical considerations by requiring that the ionization energy theorem (−ϵm=I) be satisfied as closely as possible. This method is applied to the case in which the de

Interactions of carriers with interface optical phonons dominate over other carrier–phonon scatterings in narrow quantum-well structures. Herein, a transfer matrix method is used to establish a formalism for determining the dispersion relations, el
