Preparation of Non-equilibrium Nuclear Spin States in Double Quantum Dots
M. Gullans, J. J. Krich, J. M. Taylor +2
We theoretically study the dynamic polarization of lattice nuclear spins in GaAs double quantum dots containing two electrons. In our prior work [Phys. Rev. Lett. 104, 226807 (2010…
Phase coherence in one-dimensional superconductivity by power-law hopping
Alejandro M. Lobos, Masaki Tezuka, Antonio M. García-García
In a one-dimensional (1D) superconductor, zero temperature quantum fluctuations destroy phase coherence. Here we put forward a mechanism which can restore phase coherence: power-la…
Feshbach resonances, weakly bound molecular states and coupled-channel potentials for cesium at high magnetic fields
Martin Berninger, Alessandro Zenesini, Bo Huang +6
We explore the scattering properties of ultracold ground-state Cs atoms at magnetic fields between 450 G (45 mT) and 1000 G. We identify 17 new Feshbach resonances, including two v…
Direct imaging of topological edge states in cold-atom systems
N. Goldman, J. Dalibard, A. Dauphin +4
Detecting topological order in cold-atom experiments is an ongoing challenge, the resolution of which offers novel perspectives on topological matter. In material systems, unambigu…
Quadrature interferometry for nonequilibrium ultracold bosons in optical lattices
Eite Tiesinga, Philip R. Johnson
We develop an interferometric technique for making time-resolved measurements of field-quadrature operators for nonequilibrium ultracold bosons in optical lattices. The technique e…
Generation of pulsed bipartite entanglement using four-wave mixing
Quentin Glorieux, Jeremy B. Clark, Neil V. Corzo +1
Using four-wave mixing in a hot atomic vapor, we generate a pair of entangled twin beams in the microsecond pulsed regime near the D1 line of Rb, making it compatible with c…
Quantum phases of hard-core bosons in a frustrated honeycomb lattice
Christopher N. Varney, Kai Sun, Victor Galitski +1
Using exact diagonalization calculations, we investigate the ground-state phase diagram of the hard-core Bose-Hubbard-Haldane model on the honeycomb lattice. This allows us to prob…
Spontaneous creation and persistence of ground-state coherence in a resonantly driven intra-cavity atomic ensemble
D. G. Norris, A. D. Cimmarusti, L. A. Orozco +2
The spontaneous creation and persistence of ground-state coherence in an ensemble of intracavity Rb atoms has been observed as a quantum beat. Our system realizes a quantum eraser,…
Efficient single-spatial-mode periodically-poled KTiOPO_4 waveguide source for high-dimensional entanglement-based quantum key distribution
Tian Zhong, Franco N. C. Wong, Alessandro Restelli +1
We demonstrate generation of high-purity photon pairs at 1560 nm in a single spatial mode from a periodically-poled KTiOPO_4 (PPKTP) waveguide. With nearly lossless spectral filter…
Confinement of monopoles and scaling theory near unconventional critical points
Stephen Powell
Conventional ordering transitions, described by the Landau paradigm, are characterized by the symmetries broken at the critical point. Within the constrained manifold occurring at…
Deterministic Photon Pairs via Coherent Optical Control of a Single Quantum Dot
Harishankar Jayakumar, Ana Predojević, Tobias Huber +3
The strong confinement of semiconductor excitons in a quantum dot gives rise to atom-like behavior. The full benefit of such a structure is best observed in resonant excitation whe…
Gradient echo memory in an ultra-high optical depth cold atomic ensemble
B. M. Sparkes, J. Bernu, M. Hosseini +6
Quantum memories are an integral component of quantum repeaters - devices that will allow the extension of quantum key distribution to communication ranges beyond that permissible…

We explore the time evolution of quasi-1D two component Bose-Einstein condensates (BEC's) following a quench from one component BEC's with a order parameter into two c…
Efficiency vs. multi-photon contribution test for quantum dots
Ana Predojevic, Miroslav Jezek, Tobias Huber +5
The development of linear quantum computing within integrated circuits demands high quality semiconductor single photon sources. In particular, for a reliable single photon source…
