Phase operators and blurring time of a pair-condensed Fermi gas
Hadrien Kurkjian, Yvan Castin, Alice Sinatra
Due to atomic interactions and dispersion in the total atom number, the order parameter of a pair-condensed Fermi gas experiences a collapse in a time that we derive microscopicall…
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…
Limit of spin squeezing in trapped Bose-Einstein condensates
Alice Sinatra, Yvan Castin, Emilia Witkowska
The evolution of an interacting two-component Bose-Einstein condensate from an initial phase state leads to a spin squeezed state that may be used in atomic clocks to increase the…
