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.

The manipulation of ultracold atoms of high orbitals in optical lattices
Frontiers in Physics, 2022 Ultracold atoms in optical lattices are a powerful tool for quantum simulation, precise measurement, and quantum computation. A fundamental problem in applying this quantum system is how to manipulate the higher bands or orbitals in Bloch states ...

Photoionization of Rydberg atoms in optical lattices
New Journal of Physics, 2021 We develop a formalism for photoionization (PI) and potential energy curves (PECs) of Rydberg atoms in ponderomotive optical lattices and apply it to examples covering several regimes of the optical-lattice depth.

An accordion superlattice for controlling atom separation in optical potentials
New Journal of Physics, 2023 We propose a method for separating trapped atoms in optical lattices by large distances. The key idea is the cyclic transfer of atoms between two lattices of variable spacing, known as accordion lattices, each covering at least a factor of two in lattice

Synthetic band-structure engineering in polariton crystals with non-Hermitian topological phases
Nature Communications, 2020 To simulate band structures of solid state materials synthetic lattices are usually generated by optical lattices or by irreversible patterning the system.
