Optimal atomic interferometry robust to detection noise using spin-1 atomic condensates
Artur Niezgoda, Dariusz Kajtoch, Joanna Dziekańska +1
Implementation of the quantum interferometry concept to spin-1 atomic Bose-Einstein condensates is analyzed by employing a polar state evolved in time. In order to identify the bes…
Adiabaticity when raising a uniform 3D optical lattice in a bimodal Bose-Einstein condensate
Dariusz Kajtoch, Emilia Witkowska, Alice Sinatra
Using the time-dependent Bogoliubov approach, we study adiabaticity for a two-component Bose-Einstein condensate in a 3D time-dependent optical lattice with unit filling, in the su…
Efficient two-mode interferometers with spinor Bose-Einstein condensates
Artur Niezgoda, Dariusz Kajtoch, Emilia Witkowska
We consider general three-mode interferometers using a spin-1 atomic Bose-Einstein condensate with macroscopic magnetization. We show that these interferometers, combined with the…
Metrologically useful states of spin-1 Bose condensates with macroscopic magnetization
Dariusz Kajtoch, Krzysztof Pawłowski, Emilia Witkowska
We study theoretically the usefulness of spin-1 Bose condensates with macroscopic magnetization in a homogeneous magnetic field for quantum metrology. We demonstrate Heisenberg sca…
Spin squeezing in dipolar spinor condensates
Dariusz Kajtoch, Emilia Witkowska
We study the effect of dipolar interactions on the level of squeezing in spin-1 Bose-Einstein condensates by using the single mode approximation. We limit our consideration to the…
