Dynamic and nonlinear magnetoconductance: Numerical analysis in two dimensions

Nonlinear magnetoconductance of a classical ballistic system.

We study nonlinear transport through a classical ballistic system accounting for the Coulomb interaction between electrons. The joint effect of the applied bias V and magnetic field H on the electron trajectories results in a component of the nonlinear current I(V,H) which lacks the H-->-H symmetry: deltaI=alpha(cl)V(2)H. At zero temperature the magnitude of alpha(cl) is of the same order as th...

Algorithms for Numerical Analysis in High Dimensions

Nearly every numerical analysis algorithm has computational complexity that scales exponentially in the underlying physical dimension. The separated representation, introduced previously, allows many operations to be performed with scaling that is formally linear in the dimension. In this paper we further develop this representation by (i) discussing the variety of mechanisms that allow it to b...

Dynamic glass transition in two dimensions.

The question of the existence of a structural glass transition in two dimensions is studied using mode coupling theory (MCT). We determine the explicit d dependence of the memory functional of mode coupling for one-component systems. Applied to two dimensions we solve the MCT equations numerically for monodisperse hard disks. A dynamic glass transition is found at a critical packing fraction ph...
