Frequency-to-voltage converter based on Bloch oscillations in a capacitively coupled GaAs-GaxAl1-xAs quantum well
(American Physical Society, 1993-09-15)
A charged capacitor which is placed with a semiconductor in a closed loop will normally discharge in a characteristic time τ=1/RC. We show, however, that if a semiconductor of high purity is subjected to a rf bias with ...
Stark effect in nonlinear Jaynes-Cummings models
(American Physical Society, 1993-02)
We investigate the effect of the Stark shifts on the atomic-inversion dynamics when a multilevel atom interacts with a two-mode quantized radiation field. We utilize Hamiltonians obtained by adiabatically eliminating all ...
