The geometry of D-branes can be probed by open string scattering. If the background carries a non-vanishing B-field, the world-volume becomes noncommutative. Here we explore the quantization ofâ€¦ (More)

We study transport through a semiconductor superlattice with an electric field parallel to and a magnetic field perpendicular to the growth axis. Using a semiclassical balance equation model withâ€¦ (More)

For space-times with two spacelike isometries, we present infinite hierarchies of exact solutions of the Einstein and Einstein-Maxwell equations as represented by their Ernst potentials. Thisâ€¦ (More)

This article is a review of two original papers [1], [2]. We begin with a description of Kirillov symplectic form and quantum mechanics on coadjoint orbits of a simple Lie group. This theory may beâ€¦ (More)
