We describe the coherent atomic tunneling between two Bose-Einstein condensates confined in a double-well potential, whose zero-point energies are modulated by a small oscillation of the barrier-laser position. The coupled-mode equations derived from

The tunneling motion of an electron in three coupled quantum dots forming apexes of an equilateral triangle under the action of a circularly polarized electric field is numerically studied. For the adiabatic conditions, the electron initially launche

Dynamical suppression and enhancement of the quantum tunneling in an asymmetric coupled-quantum-dot structure is predicted to occur when a laser field drives a subband transition in one of the dots. The laser field induces the splitting and shift of

We investigated the in-plane optical anisotropy of (11 N ) quantum wells both experimentally and theoretically. A high-quality GaAs/AlGaAs quantum-well structure was grown on a (113)A substrate by molecular beam epitaxy. Polarized photoluminescence m

The complex multistable responses of two bistable elements optically connected in series are theoretically analyzed. Each bistable element is a self‐electro‐optic device. The analysis is based on a phenomenological rate equation for photocarrier

Journal of Applied Physics. 75:2105-2109
The radiative transitions of (100)‐ and (311)A‐oriented three‐step asymmetric coupled quantum wells in an electric field are studied by photoluminescence. Four distinct transitions are observed in the spectra which exhibit remarkably complex en

We have investigated the Stark effect on the spectral hole characteristics in the photochemical hole burning reaction in systems of anthraquinone derivatives, such as 1,4-dihydroxyanthraquinone (DAQ) and 4-amino-2,6-bis(4-butylphenoxy)1,5-dihydroxyan
