Cooperatively-enhanced precision of hybrid light-matter sensors
A. Niezgoda, J. Chwedenczuk, T. Wasak +1
We consider a hybrid system of matter and light as a sensing device and quantify the role of cooperative effects. The latter generically enhance the precision with which modificati…
Tradeoffs for number-squeezing in collisions of Bose-Einstein condensates
P. Deuar, T. Wasak, P. Zin +2
We investigate the factors that influence the usefulness of supersonic collisions of Bose-Einstein condensates as a potential source of entangled atomic pairs by analyzing the redu…
Parameter estimation in a memory-assisted noisy quantum interferometry
P. Szankowski, M. Trippenbach, J. Chwedenczuk
We demonstrate that memory in an -qubit system subjected to decoherence, is a potential resource for the slow-down of the entanglement decay. We show that this effect can be use…
Raman scattering of atoms from a quasi-condensate in a perturbative regime
T. Wasak, J. Chwedenczuk, P. Zin +1
It is demonstrated that measurements of positions of atoms scattered from a quasi-condensate in a Raman process provide information on the temperature of the parent cloud. In parti…
Bogoliubov dynamics of condensate collisions using the positive-P representation
P. Deuar, J. Chwedenczuk, M. Trippenbach +1
We formulate the time-dependent Bogoliubov dynamics of colliding Bose-Einstein condensates in terms of a positive-P representation of the Bogoliubov field. We obtain stochastic evo…
Free-fall expansion of finite-temperature Bose-Einstein condensed gas in the non Thomas-Fermi regime
M. Zawada, R. Abdoul, J. Chwedeńczuk +5
We report on our study of the free-fall expansion of a finite-temperature Bose-Einstein condensed cloud of 87Rb. The experiments are performed with a variable total number of atoms…
