Coherent control of optical lattices and optical unit cells in atomic medium by counter propagation of Laguerre Gaussian beams [PDF]

open access: yesScientific Reports
This 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.

Quantum Gibbs distribution from dynamical thermalization in classical nonlinear lattices [PDF]

open access: yesNew Journal of Physics, 2013
We study numerically time evolution in classical lattices with weak or moderate nonlinearity which leads to interactions between linear modes. Our results show that in a certain strength range a moderate nonlinearity generates a dynamical thermalization ...

Generalized Haldane models on laser-coupling optical lattices [PDF]

open access: yesScientific 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.

Efficient and feasible state tomography of quantum many-body systems

open access: yesNew Journal of Physics, 2013
We present a novel method for performing quantum state tomography for many-particle systems, which are particularly suitable for estimating the states in lattice systems such as of ultra-cold atoms in optical lattices.

Collapse Dynamics of Vortex Beams in a Kerr Medium with Refractive Index Modulation and PT-Symmetric Lattices

open access: yesPhotonics, 2022
Using the two-dimensional nonlinear Schrödinger equation, the collapse dynamics of vortex beams in a Kerr medium with refractive index modulation and parity–time (PT) symmetric lattices are explored. The critical power for the collapse of vortex beams in

The manipulation of ultracold atoms of high orbitals in optical lattices

open access: yesFrontiers 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 ...

Cavity-Enhanced Optical Lattices for Scaling Neutral Atom Quantum Technologies to Higher Qubit Numbers

open access: yesPRX Quantum, 2022
We demonstrate a cavity-based solution to scale up experiments with ultracold atoms in optical lattices by an order of magnitude over state-of-the-art free-space lattices.

Photoionization of Rydberg atoms in optical lattices

open access: yesNew 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.
