Toroidal Transitions in Hydrogenic and Alkali Atoms
Kai Xiang Lee, Vincent Mancois, Kelvin Lim +1
In addition to electric and magnetic multipoles, the expansion of current density also yields toroidal terms, a lesser-known family of multipoles. A recent proposal, I. Kuprov $\te…
Probing atom-surface interactions from tunneling-time measurements via rotation-transport on an atom chip
J-B. Gerent, R. Veyron, V. Mancois +3
We propose a novel method to measure the interaction between an ultracold gas of neutral atoms and a surface. This solution combines an optical dipole trap reflected by the surface…
Super-resolution optical trapping of multiple cold atoms
Kelvin Lim, Vincent Mancois, Haijun Wu +2
Arrays of optical tweezers form the backbone of neutral atoms analog and digital quantum processors. However, the inter-trap distance remains generally much larger than the size of…
In situ subwavelength microscopy of ultracold atoms using dressed excited states
Romain Veyron, Jean-Baptiste Gérent, Guillaume Baclet +3
In this work, we implement a new method for imaging ultracold atoms with subwavelength resolution capabilities and determine its regime of validity. It uses the laser driven intera…
Quantitative absorption imaging of optically dense effective two-level systems
Romain Veyron, Vincent Mancois, Jean-Baptiste Gerent +3
Absorption imaging is a commonly adopted method to acquire, with high temporal resolution, spatial information on a partially transparent object. It relies on the interference betw…
Effective two-level approximation of a multi-level system driven by coherent and incoherent fields
Romain Veyron, Vincent Mancois, Jean-Baptiste Gerent +3
The numerical simulation of multiple scattering in dense ensembles is the mostly adopted solution to predict their complex optical response. While the scalar and vectorial light me…
Anisotropic long-range interaction investigated with cold atoms
Vincent Mancois, Julien Barré, Chang Chi Kwong +3
In two dimensions, a system of self-gravitating particles collapses and forms a singularity in finite time below a critical temperature . We investigate experimentally a quasi…
Two-temperature Brownian dynamics of a particle in a confining potential
Vincent Mancois, Bruno Marcos, Pascal Viot +1
We consider the two dimensional motion of a particle into a confining potential, subjected to Brownian forces, associated with two different temperatures on the orthogonal directio…
