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…
Tunneling phase gate for neutral atoms in a double-well lattice
Frederick W. Strauch, Mark Edwards, Eite Tiesinga +2
We propose a new two--qubit phase gate for ultra--cold atoms confined in an experimentally realized tilted double--well optical lattice [Sebby--Strabley et al., Phys. Rev. A {\bf 7…
Experimentally accessible reentrant phase transitions in double-well optical lattices
Ippei Danshita, Carlos A. R. Sa de Melo, Charles W. Clark
We study the quantum phases of bosons confined in a combined potential of a one-dimensional double-well optical lattice and a parabolic trap. We apply the time-evolving block decim…
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…
Blackbody radiation shift in a 43Ca+ ion optical frequency standard
Bindiya Arora, M. S. Safronova, Charles W. Clark
Motivated by the prospect of an optical frequency standard based on 43Ca+, we calculate the blackbody radiation (BBR) shift of the 4s_1/2-3d_5/2 clock transition, which is a major…
Magic wavelengths for the np-ns transitions in alkali-metal atoms
Bindiya Arora, M. S. Safronova, Charles W. Clark
Extensive calculations of the electric-dipole matrix elements in alkali-metal atoms are conducted using the relativistic all-order method. This approach is a linearized version of…
