Drag in paired electron-hole layers
Giovanni Vignale, A. H. MacDonald
We investigate transresistance effects in electron-hole double layer systems with an excitonic condensate. Our theory is based on the use of a minimum dissipation premise to fix th…
Current-Carrying Ground States in Mesoscopic and Macroscopic Systems
Michael R. Geller
We extend a theorem of Bloch, which concerns the net orbital current carried by an interacting electron system in equilibrium, to include mesoscopic effects. We obtain a rigorous u…
Quantum Breathing Mode for Electrons with 1/r^2 Interaction
Michael R. Geller, Giovanni Vignale
We discuss a collective "breathing" mode of electrons with inverse-square-law interactions in a two-dimensional quantum dot and a perpendicular magnetic field.
Inequalities of correlation type for symmetric stable random vectors
Alexander Koldobsky, Stephen J. Montgomery-Smith
We prove that, for any jointly stable random variables with zero mean, any and any even continuous positive definite functions and on an…
Equilibrium Current and Orbital Magnetization in a Quantum Hall Fluid
Michael R. Geller, Giovanni Vignale
We present a general theory for the equilibrium current distribution in an interacting two-dimensional electron gas subjected to a perpendicular magnetic field, and confined by a p…
Spaces of Geodesics: Products, Coverings, Connectedness
J. K. Beem, R. J. Low, P. E. Parker
We continue our study of the space of geodesics of a manifold with linear connection. We obtain sufficient conditions for a product to have a space of geodesics which is a manifold…
