Effective Faraday interaction between light and nuclear spins of Helium-3 in its ground state: a semiclassical study
Matteo Fadel, Philipp Treutlein, Alice Sinatra
We derive the semiclassical evolution equations for a system consisting of helium-3 atoms in the metastable state interacting with a light field far-detuned from the $2^3S-2…
EPR-entangled Bose-Einstein condensates in state-dependent potentials: a dynamical study
Hadrien Kurkjian, Krzysztof Pawlowski, Alice Sinatra
We study generation of non-local correlations by atomic interactions in a pair of bi-modal Bose-Einstein Condensates in state-dependent potentials including spatial dynamics. The w…
Quantum-enhanced multiparameter estimation and compressed sensing of a field
Youcef Baamara, Manuel Gessner, Alice Sinatra
We show that a significant quantum gain corresponding to squeezed or over-squeezed spin states can be obtained in multiparameter estimation by measuring the Hadamard coefficients o…
Spin Squeezing in Finite Temperature Bose-Einstein Condensates : Scaling with the system size
Alice Sinatra, Emilia Witkowska, Yvan Castin
We perform a multimode treatment of spin squeezing induced by interactions in atomic condensates, and we show that, at finite temperature, the maximum spin squeezing has a finite l…
Spin squeezing and EPR entanglement of two bimodal condensates in state-dependent potentials
Hadrien Kurkjian, Krzysztof Pawlowski, Philipp Treutlein +1
We propose and analyze a scheme to entangle the collective spin states of two spatially separated bimodal Bose-Einstein condensates. Using a four-mode approximation for the atomic…
A classical field method for time dependent Bose condensed gases
Alice Sinatra, Carlos Lobo, Yvan Castin
We propose a method to study the time evolution of Bose condensed gases perturbed from an initial thermal equilibrium, based on the Wigner representation of the -body density op…
