Direct loading of Yb atoms into a 3D magneto-optical trap from a dispenser atomic source
AIP Advances, 2023 The realization of cold atoms using a compact and low-power-consumption experimental setup is indispensable for cold atom experiments, including optical clocks and quantum simulations.

Resonant interaction of trapped cold atoms with a magnetic cantilever tip [PDF]
, 2015 Magnetic resonance in an ensemble of laser-cooled trapped Rb atoms is excited using a micro- cantilever with a magnetic tip. The cantilever is mounted on a multi-layer chip designed to capture, cool, and magnetically transport cold atoms. The coupling is

Cold-atom optical filtering enhanced by optical pumping
Frontiers in Physics, 2022 Atomic optical filters such as Faraday anomalous dispersion optical filters (FADOFs) or similar technologies can achieve very narrow optical bandwidth close to the scale of atomic linewidth, which can be greatly reduced in cold atoms. However, limited by

Sympathetic and swap cooling of trapped ions by cold atoms in a MOT [PDF]
, 2011 A mixed system of cooled and trapped, ions and atoms, paves the way for ion assisted cold chemistry and novel many body studies. Due to the different individual trapping mechanisms, trapped atoms are significantly colder than trapped ions, therefore in ...

Photoassociation spectroscopy of cold calcium atoms [PDF]
, 2002 Photoassociation spectroscopy experiments on 40Ca atoms close to the dissociation limit 4s4s 1S0 - 4s4p 1P1 are presented. The vibronic spectrum was measured for detunings of the photoassociation laser ranging from 0.6 GHz to 68 GHz with respect to the ...

Mean-Field Description of Cooperative Scattering by Atomic Clouds
Atoms, 2023 We present analytic expressions for the scattering of light by an extended atomic cloud. We obtain the solution for the mean-field excitation of different atomic spherical distributions driven by a uniform laser, including the initial build up, the ...

Combined ion and atom trap for low temperature ion-atom physics
, 2011 We report an experimental apparatus and technique which simultaneously traps ions and cold atoms with spatial overlap. Such an apparatus is motivated by the study of ion-atom processes at temperatures ranging from hot to ultra-cold.

Quantum simulation of non-trivial topology
New Journal of Physics, 2015 We propose several designs to simulate quantum many-body systems in manifolds with a non-trivial topology. The key idea is to create a synthetic lattice combining real-space and internal degrees of freedom via a suitable use of induced hoppings.

Artificial atoms from cold bosons in one dimension
New Journal of Physics, 2022 We investigate the ground-state properties of weakly repulsive one-dimensional bosons in the presence of an attractive zero-range impurity potential. First, we derive mean-field solutions to the problem on a finite ring for the two asymptotic cases: (i ...
