Abstract

We demonstrate a simple, all-optical technique to prepare and determine the desired internal quantum states in multi-Zeeman-sublevel atoms. By choosing appropriate coupling and pumping laser beams, atoms can be easily prepared in a desired Zeeman sublevel with high purity or in any chosen ground-state population distributions (spin-polarized quantum-state engineering). The population distributions or state purities of such prepared atomic states can be determined by using a weak, circularly polarized probe beam due to differences in transition strengths among different Zeeman sublevels. This technique will have potential impact on quantum-information processing in multilevel atomic systems.

Controlled polarization rotation of an optical field in multi-Zeeman-sublevel atoms

Journal Article Li Shujing ; Wang Bo ; Yang Xudong ; ... - Physical Review. A

We investigate, both theoretically and experimentally, the phenomenon of polarization rotation of a weak, linearly polarized optical (probe) field in an atomic system with multiple three-level electromagnetically induced transparency (EIT) subsystems. The polarization rotation angle can be controlled by a circularly polarized coupling beam, which breaks the symmetry in number of EIT subsystems seen by the left and right circularly polarized components of the weak probe beam. A large polarization rotation angle (up to 45 deg. ) has been achieved with a coupling beam power of only 15 mW.

Rotating Ground States of a One-Dimensional Spin-Polarized Gas of Fermionic Atoms with Attractive p-Wave Interactions on a Mesoscopic Ring

Journal Article Girardeau, M. D. ; Wright, E. M. ; Department of Physics, University of Arizona, Tucson, Arizona 85721 - Physical Review Letters

The major finding of this Letter is that a one-dimensional spin-polarized gas composed of an even number of fermionic atoms interacting via attractive p-wave interactions and confined to a mesoscopic ring has a degenerate pair of ground states that are oppositely rotating. In any realization the gas will be measured to rotate one way or the other in spite of the fact that there is no external rotation or bias fields. Our goal is to show that this counterintuitive finding is a natural consequence of the combined effects of quantum statistics, ring topology, and exchange interactions.

Spin polarized current from multiply-coupled rings with Zeeman-split quantum dots

Journal Article Hedin, Eric R. ; Joe, Yong S. - Journal of Applied Physics

We investigate transmission resonances and conductance properties of multiple, serially connected, direct-contact nanoscale rings using the tight-binding model. Quantum dots (QDs) are embedded in the two arms of each ring, and Zeeman-splitting of the QD energy levels is incorporated into the system Hamiltonian. Transmission bands develop as the number of rings in series increases, with a band-gap which is sensitive to the degree of Zeeman splitting and the initial settings of the QD site energy values. The current vs. voltage characteristics of the system can be modulated between Ohmic and semiconducting as a function of the Zeeman splitting. In addition,more »« less

Angle-differential cross sections and spin-asymmetry parameters for spin-polarized electron-impact excitation of spin-polarized cesium atoms

Journal Article Baum, G. ; Foerster, S. ; Pavlovic, N. ; ... - Physical Review. A

Relative angle-differential cross sections and spin-asymmetry parameters are presented for spin-polarized electron-impact excitation of spin-polarized cesium atoms for incident projectile energies ranging from 5 eV to 25 eV. The experimental data, obtained in the angular range of 40 deg. to 140 deg., are compared with predictions from a nonrelativistic convergent close-coupling treatment for the differential cross section and the (spin) exchange asymmetry and from a semirelativistic R matrix with pseudostates approach. The latter also yields nonzero values for two other spin asymmetries that require the presence of explicitly relativistic effects such as the spin-orbit interaction. The overall agreement between themore »« less
