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 ...

Fully Frustrated Cold Atoms

, 2005
Fully frustrated Josephson Junction arrays (FF-JJA's) exhibit a subtle compound phase transition in which an Ising transition associated with discrete broken translational symmetry and a Berezinskii-Kosterlitz-Thouless (BKT) transition associated with ...

Macroscopic magnetic guide for cold atoms [PDF]

, 2009
We demonstrate a macroscopic magnetic guide for cold atoms with suppressed longitudinal field curvature which is highly desired for atom interferometry.

Dark Optical Lattice of Ring Traps for Cold Atoms [PDF]

, 2006
We propose a new geometry of optical lattice for cold atoms, namely a lattice made of a 1D stack of dark ring traps. It is obtained through the interference pattern of a standard Gaussian beam with a counter-propagating hollow beam obtained using a setup

Simultaneous deceleration of atoms and molecules in a supersonic beam

New Journal of Physics, 2015
A unique property of Zeeman effect based manipulation of paramagnetic particle’s motion is the ability to control velocities of both atoms and molecules.

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 ...

Stationary Light Pulses in Cold Atomic Media

, 2008
Stationary light pulses (SLPs), i.e., light pulses without motion, are formed via the retrieval of stored probe pulses with two counter-propagating coupling fields.

Exotic Superfluidity in Cold Atoms [PDF]

Crossing the Boundaries, 2010
We derived the low energy effective action for the collective modes in asymmetric fermionic systems with attractive interaction. We obtained the phase diagram in terms of the chemical potentials. It features a stable gapless superfluidity with one Fermi surface on the BEC side of the resonance.
