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…
