Splitting of Majorana modes due to intervortex tunneling in a p + ip superconductor
Meng Cheng, Roman M. Lutchyn, Victor Galitski +1
We consider a two-dimensional px+i py superconductor in the presence of multiple vortices, which support zero-energy Majorana fermion states in their cores. Intervortex tunnelings…
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…
Quantum decoherence of a charge qubit in a spin-fermion model
R. M. Lutchyn, L. Cywinski, Cody P. Nave +1
We consider quantum decoherence in solid-state systems by studying the transverse dynamics of a single qubit interacting with a fermionic bath and driven by external pulses. Our in…
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…
How to Enhance Dephasing Time in Superconducting Qubits
L. Cywinski, R. M. Lutchyn, C. P. Nave +1
We theoretically investigate the influence of designed pulse sequences in restoring quantum coherence lost due to background noise in superconducting qubits. We consider both 1/f n…
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…
