Decoherence without dissipation?
Dominique Gobert, Jan von Delft, Vinay Ambegaokar
In a recent article, Ford, Lewis and O'Connell (PRA 64, 032101 (2001)) discuss a thought experiment in which a Brownian particle is subjected to a double-slit measurement. Analyzin…
Interaction Induced Restoration of Phase Coherence
A. A. Clerk, P. W. Brouwer, V. Ambegaokar
We study the conductance of a quantum T-junction coupled to two electron reservoirs and a quantum dot. In the absence of electron-electron interactions, the conductance is sens…
Width and Magnetic Field Dependence of Transition Temperature in Ultranarrow Superconducting Wires
Robert A Smith, Beccy S Handy, Vinay Ambegaokar
We calculate the transition temperature in ultranarrow superconducting wires as a function of wire width, resistance and applied magnetic field. We compare the results of first-ord…
Charge Pumping and Photovoltaic effect in Open Quantum Dots
Maxim G. Vavilov, V. Ambegaokar, Igor L. Aleiner
We propose a random matrix theory to describe the influence of a time-dependent external field on electron transport through open quantum dots. We describe the generation of the cu…
Andreev Conductance of Chaotic and Integrable Quantum Dots
A. A. Clerk, P. W. Brouwer, V. Ambegaokar
We examine the voltage V and magnetic field B dependent Andreev conductance of a chaotic quantum dot coupled via point contacts to a normal metal and a superconductor. In the case…
Effect of Level Statistics on Superconductivity in Ultrasmall Metallic Grains
Robert A. Smith, Vinay Ambegaokar
We examine the destruction of superconducting pairing in metallic grains as their size is decreased for both even and odd numbers of electrons. This occurs when the average level s…
