Theory of long-range ultracold atom-molecule photoassociation

open access: yes, 2015
The creation of ultracold molecules is currently limited to diatomic species. In this letter we present a theoretical description of the photoassociation of ultracold atoms and molecules to create ultracold excited triatomic molecules, thus being a novel

Ultracold few fermionic atoms in needle-shaped double wells: spin chains and resonating spin clusters from microscopic Hamiltonians emulated via antiferromagnetic Heisenberg and t–J models

open access: yesNew Journal of Physics, 2016
Advances with trapped ultracold atoms intensified interest in simulating complex physical phenomena, including quantum magnetism and transitions from itinerant to non-itinerant behavior.

Quantum simulation of conductivity plateaux and fractional quantum Hall effect using ultracold atoms

open access: yesNew Journal of Physics, 2015
We analyze the role of impurities in the fractional quantum Hall effect using a highly controllable system of ultracold atoms. We investigate the mechanism responsible for the formation of plateaux in the resistivity/conductivity as a function of the ...

Third-order spatial correlations for ultracold atoms

open access: yesNew Journal of Physics, 2013
We present here the first measurement of the third-order spatial correlation function for atoms, made possible by cooling a metastable helium cloud to create an ultracold thermal ensemble just above the Bose–Einstein condensation point.

Cavity-controlled formation of ultracold molecules

open access: yesNew Journal of Physics, 2018
Ultracold ground-state molecules can be formed from ultracold atoms via photoassociation followed by a spontaneous emission process. Typically, the molecular products are distributed over a range of final states. Here, we propose to use an optical cavity

Generating an effective magnetic lattice for ultracold atoms

open access: yesNew Journal of Physics, 2015
We present a general scheme for synthesizing a spatially periodic magnetic field, or a magnetic lattice (ML), for ultracold atoms using pulsed gradient magnetic field (GMF). Our scheme is immune to atomic spontaneous emission often encountered in optical

Scanning tunneling microscopy for ultracold atoms

open access: yesPhysical Review A, 2007
We propose a novel experimental probe for cold atomic gases analogous to the scanning tunnelling microscope (STM) in condensed matter. This probe uses the coherent coupling of a single particle to the system. Depending on the measurement sequence, our probe allows to either obtain the \emph{local} density, with a resolution on the nanometer scale, or ...

Chiral magnetic effect in three-dimensional optical lattices

open access: yesPhysical Review Research, 2019
Although Weyl semimetals have been extensively studied for exploring rich topological physics, the direct observation of the celebrated chiral magnetic effect (CME) associated with the so-called dipolar chiral anomaly has long intrigued and challenged ...
