Spin squeezing in Bose-Einstein condensates: Limits imposed by decoherence and non-zero temperature
Alice Sinatra, Jean-Christophe Dornstetter, Yvan Castin
We consider dynamically generated spin squeezing in interacting bimodal condensates. We show that particle losses and non-zero temperature effects in a multimode theory completely…

Limit of Spin Squeezing in Finite Temperature Bose-Einstein Condensates
Alice Sinatra, Emilia Witkowska, Jean-Christophe Dornstetter +2
We show that, at finite temperature, the maximum spin squeezing achievable using interactions in Bose-Einstein condensates has a finite limit when the atom number at…
