Intravalley Multiple Scattering of Quasiparticles in Graphene
J. Y. Vaishnav, Justin Q. Anderson, Jamie D. Walls
We develop a theoretical description of intravalley scattering of quasiparticles in graphene from multiple short-range scatterers of size much greater than the carbon-carbon bond l…
Topological Insulators and Metals in Atomic Optical Lattices
Tudor D. Stanescu, Victor Galitski, J. Y. Vaishnav +2
We propose the realization of topological quantum states with cold atoms trapped in an optical lattice. We discuss an experimental setup that generates a two-dimensional hexagonal…
Spin Field Effect Transistors with Ultracold Atoms
J. Y. Vaishnav, Julius Ruseckas, Charles W. Clark +1
We propose a method of constructing cold atom analogs of the spintronic device known as the Datta-Das transistor (DDT), which despite its seminal conceptual role in spintronics, ha…
Observing Zitterbewegung in Ultracold Atoms
J. Y. Vaishnav, Charles W. Clark
We propose an optical lattice scheme which would permit the experimental observation of Zitterbewegung (ZB) with ultracold, neutral atoms. A four-level "tripod" variant of the usua…
Two-Dimensional Electron Gas with Cold Atoms in Non-Abelian Gauge Potentials
Indubala I. Satija, Daniel C. Dakin, J. Y. Vaishnav +1
Motivated by the possibility of creating non-Abelian fields using cold atoms in optical lattices, we explore the richness and complexity of non-interacting two-dimensional electron…
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…
