Optical coherence gratings and lattices [PDF]
Optics Letters, 2014 We introduce a class of partially coherent temporal/spatial sources, optical coherence gratings/lattices that have a Gaussian intensity profile and statistically stationary/homogeneous, periodic temporal/spatial coherence properties.

Coherent control of optical lattices and optical unit cells in atomic medium by counter propagation of Laguerre Gaussian beams [PDF]
Scientific ReportsThis manuscript explores the coherent control of optical lattices and optical unit cells. Optical lattices are formed by the counter-propagation of Laguerre Gaussian beams within an atomic medium.

Generalized Haldane models on laser-coupling optical lattices [PDF]
Scientific Reports, 2018 We propose two generalized Haldane models on laser-coupling optical lattices. Laser-assisted nearest neighbour tunnelings generate artificial staggered magnetic flux, facilitating the realization of topological nontrivial band structures.

Dynamically reconfigurable optical lattices
Optics Express, 2016 We present a theoretical framework for two approaches of generating light-efficient optical lattices via a generic Fourier-filtering operation. We demonstrate how lattice geometry can be dynamically changed from fully discrete to interconnected ...

Quantum billiards in optical lattices [PDF]
EPL (Europhysics Letters), 2009 We study finite two-dimensional spin lattices with definite geometry (spin billiards) demonstrating the display of collective integrable or chaotic dynamics depending on their shape.
