Simulation of open quantum systems
Florian Mintert, Eric J. Heller
We present an approach for the semiclassical treatment of open quantum systems. An expansion into localized states allows restriction of a simulation to a fraction of the environme…
Matter Wave Scattering and Guiding by Atomic Arrays
J. Y. Vaishnav, J. D. Walls, M. Apratim +1
We investigate the possibility that linear arrays of atoms can guide matter waves, much as fiber optics guide light. We model the atomic line as a quasi-1D array of s wave point sc…
Imaging coherent electron wave flow in a two-dimensional electron gas
B. J. LeRoy, A. C. Bleszynski, M. A. Topinka +5
We measure the energy distribution of electrons passing through a two-dimensional electron gas using a scanning probe microscope. We present direct spatial images of coherent elect…
Statistical Distribution of Coulomb Blockade Peak Heights in Adiabatically Pumped Quantum Dots
M. Blaauboer, E. J. Heller
We study adiabatic quantum pumping in the resonant tunneling regime of a nearly-closed quantum dot, which is coupled to two leads via tunneling barriers. Using small cyclic variati…
Parametric Evolution for a Deformed Cavity
Doron Cohen, Alex Barnett, Eric J. Heller
We consider a classically chaotic system that is described by a Hamiltonian H(Q,P;x), where (Q,P) describes a particle moving inside a cavity, and x controls a deformation of the b…
Mesoscopic scattering in the half-plane: squeezing conductance through a small hole
A. H. Barnett, M. Blaauboer, A. Mody +1
We model the 2-probe conductance of a quantum point contact (QPC), in linear response. If the QPC is highly non-adiabatic or near to scatterers in the open reservoir regions, then…
