Quantum Many-Body Dynamics of Coupled Double-Well Superlattices
(American Physical Society, 2008)
We propose a method for controllable generation of non-local entangled pairs using spinor atoms loaded in an optical superlattice. Our scheme iteratively increases the distance between entangled atoms by controlling the ...
Alkaline-Earth-Metal Atoms as Few-Qubit Quantum Registers
(American Physical Society, 2009)
We propose and analyze a novel approach to quantum information processing, in which multiple qubits can be encoded and manipulated using electronic and nuclear degrees of freedom associated with individual alkaline-earth ...
Quantum Correlation in Disordered Spin Systems: Applications to Magnetic Sensing
(American Physical Society, 2009)
We propose a strategy to generate a many-body entangled state in a collection of randomly placed, dipolarly coupled electronic spins in the solid state. By using coherent control to restrict the evolution into a suitable ...
Photon-Photon Interactions via Rydberg Blockade
(American Physical Society, 2011)
We develop the theory of light propagation under the conditions of electromagnetically induced transparency in systems involving strongly interacting Rydberg states. Taking into account the quantum nature and the spatial ...
Majorana Fermions in Equilibrium and Driven Cold Atom Quantum Wires
(American Physical Society, 2011)
We introduce a new approach to create and detect Majorana fermions using optically trapped 1D fermionic atoms. In our proposed setup, two internal states of the atoms couple via an optical Raman transition--simultaneously ...
Tunable Superfluidity and Quantum Magnetism with Ultracold Polar Molecules
(American Physical Society, 2011)
By selecting two dressed rotational states of ultracold polar molecules in an optical lattice, we obtain a highly tunable generalization of the \(t-J\) model, which we refer to as the \(t-J-V-W\) model. In addition to XXZ ...
Realization of Coherent Optically Dense Media via Buffer-Gas Cooling
(American Physical Society, 2009)
We demonstrate that buffer-gas cooling combined with laser ablation can be used to create coherent optical media with high optical depth and low Doppler broadening that offers metastable states with low collisional and ...
Quantum Spin Dynamics of Mode-Squeezed Luttinger Liquids in Two-Component Atomic Gases
(American Physical Society, 2008)
We report on the observation of the phase dynamics of interacting one-dimensional ultracold bosonic gases with two internal degrees of freedom. By controlling the non-linear atomic interactions close to a Feshbach resonance ...
Preparation of decoherence-free cluster states with optical superlattices
(Ameican Physical Society, 2009)
We present a protocol to prepare decoherence-free cluster states using ultracold atoms loaded in a two dimensional superlattice. The superlattice geometry leads to an array of 2×2 plaquettes, each of them holding four ...
Theory of Cavity-Assisted Microwave Cooling of Polar Molecules
(Institute of Physics, 2008)
We analyze cavity-assisted cooling schemes for polar molecules in the microwave domain, where molecules are excited on a rotational transition and energy is dissipated via strong interactions with a lossy stripline cavity, ...
