Decoherence and momentum relaxation in Fermi-polaron Rabi dynamics: a kinetic equation approach
Tomasz Wasak, Matteo Sighinolfi, Johannes Lang +2
Despite the paradigmatic nature of the Fermi-polaron model, the theoretical description of its nonlinear dynamics poses challenges. Here, we apply a quantum kinetic theory of drive…
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…
Quantum droplets in a dipolar Bose gas at a dimensional crossover
Pawel Zin, Maciej Pylak, Tomasz Wasak +2
We study the beyond-mean-field corrections to the energy of a dipolar Bose gas confined to two dimensions by a box potential with dipoles oriented in plane. At a critical strength…
Pair correlation of atoms scattered from colliding Bose-Einstein quasicondensates
Pawel Zin, Tomasz Wasak, Denis Boiron +1
A collision of Bose-Einstein condensates is a useful source of single nonclassically correlated pairs of atoms. Here, we consider elastic scattering of atoms from elongated clouds…
Quantum Bose-Bose droplets at a dimensional crossover
Paweł Ziń, Maciej Pylak, Tomasz Wasak +2
We study a liquid quantum droplets in a mixture of two-component Bose-Einstein condensates under a variable confinement introduced along one or two spatial dimensions. Despite the…
Properties of atomic pairs produced in the collision of Bose-Einstein condensates
Pawel Zin, Tomasz Wasak
Collisions of Bose-Einstein condensates can be used as a mean to generate correlated pairs of atoms. The scattered massive particles, in analogy to photon pairs in quantum optics,…
Bogoliubov theory for atom scattering into separate regions
T. Wasak, P. Szankowski, R. Bücker +2
We review the Bogoliubov theory in the context of recent experiments, where atoms are scattered from a Bose-Einstein Condensate into two well-separated regions. We find the full dy…
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…
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…
