Multipole expansion for dispersion forces -- watch this trace
Jivesh Kaushal, Chris Boldt, Stefan Scheel +2
Light-matter interaction models invariably rely on the multipole expansion of the electromagnetic potentials generated by complex charge distributions. These multipoles are typical…
Selective reflection Casimir-Polder spectroscopy in vapor cells: the influence of the thermal velocity distribution
B. Dutta, C. Boldt, G. Garcia-Arellano +4
Selective reflection is a high-resolution spectroscopic method that allows the probing of atomic and molecular gases in the near field of dielectric cell windows. It is a sensitive…
Coherent control over the high-dimensional space of the nuclear spin of alkaline-earth atoms
Husain Ahmed, Andrea Litvinov, Pauline Guesdon +5
We demonstrate coherent manipulation of the nuclear degrees of freedom of ultracold ground-state strontium 87 atoms, thus providing a toolkit for fully exploiting the corresponding…
Cooperative atomic emission from a line of atoms interacting with a resonant plane surface
Michelle O. Araujo, Joao Carlos de Aquino Carvalho, Philippe W. Courteille +1
Cooperative effects such as super- and subradiance can be observed in the fluorescence emitted by a system of N atoms in vacuum, after interaction with a laser beam. In the vicinit…
Effective light-induced Hamiltonian for atoms with large nuclear spin
Domantas Burba, Hubert Dunikowski, Martin Robert-de-Saint-Vincent +2
Ultra-cold fermionic atoms, having two valence electrons, exhibit a distinctive internal state structure, wherein the nuclear spin becomes decoupled from the electronic degrees of…
A method to discriminate between localized and chaotic quantum systems
Youssef Aziz Alaoui, Bruno Laburthe-Tolra
We study whether a generic isolated quantum system initially set out of equilibrium can be considered as localized close to its initial state. Our approach considers the time evolu…
