Evolution of entanglement under an Ising-like Hamiltonian with particle losses
Konrad Szymański, Krzysztof Pawłowski
We present analytical compact solution for the density matrix and correlation functions of two collective-macroscopic spins evolving via Ising-like Hamiltonian in the presence of p…
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…
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…
Mesoscopic quantum superpositions in bimodal Bose-Einstein condensates: decoherence and strategies to counteract it
Krzysztof Pawlowski, Matteo Fadel, Philipp Treutlein +2
We study theoretically the interaction-induced generation of mesoscopic coherent spin state superpositions (small cat states) from an initial coherent spin state in bimodal Bose-Ei…
