Sisyphus Optical Lattice Decelerator [PDF]
Physical Review A, 2018 We experimentally demonstrate a variation on a Sisyphus cooling technique that was proposed for cooling antihydrogen. In our implementation, atoms are selectively excited to an electronic state whose energy is spatially modulated by an optical lattice ...

Programming an optical lattice interferometer
Materials Today QuantumProgramming a quantum device describes the usage of quantum logic gates, agnostic of hardware specifics, to perform a sequence of operations with (typically) a computing or sensing task in mind.

Optical Lattice with Torus Topology. [PDF]
Phys Rev Lett, 2018 We propose an experimental scheme to construct an optical lattice where the atoms are confined to the surface of a torus. This construction can be realized with spatially shaped laser beams which could be realized with recently developed high resolution imaging techniques.

Observation of Vortex Pinning in Bose-Einstein Condensates [PDF]
, 2006 We report the observation of vortex pinning in rotating gaseous Bose-Einstein condensates (BEC). The vortices are pinned to columnar pinning sites created by a co-rotating optical lattice superimposed on the rotating BEC.

Dipolar Molecules in Optical Lattices [PDF]
Physical Review Letters, 2012 We study the extended Bose--Hubbard model describing an ultracold gas of dipolar molecules in an optical lattice, taking into account all on-site and nearest-neighbor interactions, including occupation-dependent tunneling and pair tunneling terms. Using exact diagonalization and the multiscale entanglement renormalization ansatz, we show that these ...

Anyonic braiding in optical lattices [PDF]
Proceedings of the National Academy of Sciences, 2007 Topological quantum states of matter, both Abelian and non-Abelian, are characterized by excitations whose wavefunctions undergo nontrivial statistical transformations as one excitation is moved (braided) around another. Topological quantum computation proposes to use the topological protection and the braiding statistics of a non-Abelian topological ...

Optical vortex lattice: an exploitation of orbital angular momentum
Nanophotonics, 2021 Generally, an optical vortex lattice (OVL) is generated via the superposition of two specific vortex beams. Thus far, OVL has been successfully employed to trap atoms via the dark cores.
