Image Storage in Hot Vapors

L. Zhao, T. Wang, Y. Xiao +1

We theoretically investigate image propagation and storage in hot atomic vapor. A system is adopted for imaging and an atomic vapor cell is placed over the transform plane. Th…

Diffusion induced decoherence of stored optical vortices

T. Wang, L. Zhao, L. Jiang +1

We study the coherence properties of optical vortices stored in atomic ensembles. In the presence of thermal diffusion, the topological nature of stored optical vortices is found n…

Fast mode of rotating atoms in one-dimensional lattice rings

T. Wang, S. F. Yelin

We study the rotation of atoms in one-dimensional lattice rings. In particular, the "fast mode", where the ground state atoms rotate faster than the stirring rotating the atoms, is…

Dynamics and Control of a Quasi-1D Spin System

Paola Cappellaro, Chandrasekhar Ramanathan, David G. Cory

We study experimentally a system comprised of linear chains of spin-1/2 nuclei that provides a test-bed for multi-body dynamics and quantum information processing. This system is a…

Simulations of Information Transport in Spin Chains

Paola Cappellaro, Chandrasekhar Ramanathan, David G. Cory

Transport of quantum information in linear spin chains has been the subject of much theoretical work. Experimental studies by nuclear spin systems in solid-state by NMR (a natural…

Tunable negative refraction without absorption via electromagnetically induced chirality

Jürgen Kästel, Michael Fleischhauer, Susanne F. Yelin +1

We show that negative refraction with minimal absorption can be obtained by means of quantum interference effects similar to electromagnetically induced transparency. Coupling a ma…

Optimal control of light pulse storage and retrieval

Irina Novikova, Alexey V. Gorshkov, David F. Phillips +3

We demonstrate experimentally a procedure to obtain the maximum efficiency for the storage and retrieval of light pulses in atomic media. The procedure uses time reversal to obtain…
