Properties of an electron in a quantum double well driven by a strong laser: Localization, low-frequency, and even-harmonic generation
R Bavli, H Metiu - Physical Review A, 1993 - APS
We study how a strong semi-infinite laser pulse affects an electron confined by a potential
whose parameters mimic an AlAs-GaAs-AlAs double quantum well. Interesting phenomena …

Strongly driven quantum wells: an analytical solution to the time-dependent Schrödinger equation
M Wagner - Physical review letters, 1996 - APS
An analytical solution is found for the lowest Floquet state in a single quantum well which is
strongly driven by an external laser field of form eFz cos ω t. The spectral weights of the …

Coherent and incoherent chaotic tunneling near singlet-doublet crossings
In the spectrum of systems showing chaos-assisted tunneling, three-state crossings are
formed when a chaotic singlet intersects a tunnel doublet. We study the dissipative quantum …

Driven tunnelling with dissipation
T Dittrich, B Oelschlägel, P Hänggi - Europhysics Letters, 1993 - iopscience.iop.org
We study the quantal dynamics of a harmonically driven quartic double well in the presence
of dissipation. A master equation for the reduced density operator is derived in the Floquet …

Tunneling and the onset of chaos in a driven bistable system
R Utermann, T Dittrich, P Hänggi - Physical Review E, 1994 - APS
We study the interplay between coherent transport by tunneling and diffusive transport
through classically chaotic phase-space regions, as it is reflected in the Floquet spectrum of …
