Optical Tautochrone and Squeezing Dynamics in Nonuniform Lattices
Ioannis Kiorpelidis, Matthias Heinrich, Alexander Szameit +2
We present exact analogies between the tautochrone problem of classical mechanics and the squeezed states of quantum optics to optical lattices. Both phenomena emerge in the same p…
Light-induced fictitious magnetic fields for quantum storage in cold atomic ensembles
Jianmin Wang, Liang Dong, Xingchang Wang +4
In this work, we have demonstrated that optically generated fictitious magnetic fields can be utilized to extend the lifetime of quantum memories in cold atomic ensembles. All the…
Spatiotemporal single-photon Airy bullets
Jianmin Wang, Ying Zuo, Xingchang Wang +3
Uninhibited control of the complex spatiotemporal quantum wavefunction of a single photon has so far remained elusive even though it can dramatically increase the encoding flexibil…
Quantum Interference between Photons and Single Quanta of Stored Atomic Coherence
Xingchang Wang, Jianmin Wang, Zhiqiang Ren +4
Essential for building quantum networks over remote independent nodes, the indistinguishability of photons has been extensively studied by observing the coincidence dip in the Hong…
Microscope objective for imaging atomic strontium with 0.63 micrometer resolution
Ivo Knottnerus, Sergey Pyatchenkov, Oleksiy Onishchenko +3
Imaging and manipulating individual atoms with submicrometer separation can be instrumental for quantum simulation of condensed matter Hamiltonians and quantum computation with neu…
The frequency of the ultranarrow transition in
Oleksiy Onishchenko, Sergey Pyatchenkov, Alexander Urech +4
We determine the frequency of the ultranarrow transition by spectroscopy of an ultracold gas. This transition is referenc…
Adiabatic cooling of bosons in lattices to magnetic ordering
Johannes Schachenmayer, David M. Weld, Hirokazu Miyake +3
We suggest and analyze a new scheme to adiabatically cool bosonic atoms to picokelvin temperatures which should allow the observation of magnetic ordering via superexchange in opti…
Spin-orbit coupling and spin Hall effect for neutral atoms without spin-flips
Colin J. Kennedy, Georgios A. Siviloglou, Hirokazu Miyake +2
We propose a scheme which realizes spin-orbit coupling and the spin Hall effect for neutral atoms in optical lattices without relying on near resonant laser light to couple differe…
Realizing the Harper Hamiltonian with Laser-Assisted Tunneling in Optical Lattices
Hirokazu Miyake, Georgios A. Siviloglou, Colin J. Kennedy +2
We experimentally implement the Harper Hamiltonian for neutral particles in optical lattices using laser-assisted tunneling and a potential energy gradient provided by gravity or m…
Bragg Scattering as a Probe of Atomic Wavefunctions and Quantum Phase Transitions in Optical Lattices
Hirokazu Miyake, Georgios A. Siviloglou, Graciana Puentes +3
We have observed Bragg scattering of photons from quantum degenerate Rb atoms in a three-dimensional optical lattice. Bragg scattered light directly probes the microscopic c…
