Spin-squeezed atomic crystal
Dariusz Kajtoch, Emilia Witkowska, Alice Sinatra
We propose a method to obtain a regular arrangement of two-level atoms in a three-dimensional optical lattice with unit filling, where all the atoms share internal state coherence…
Continuum of classical-field ensembles from canonical to grand canonical and the onset of their equivalence
J. Pietraszewicz, E. Witkowska, P. Deuar
The canonical and grand-canonical ensembles are two usual marginal cases for ultracold Bose gases, but real collections of experimental runs commonly have intermediate properties.…
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…
