Quantum versus classical angular momentum
Jan Mostowski, Joanna Pietraszewicz
Angular momentum in classical and quantum mechanics is carried out beyond textbooks frames. We compare angular distribution of particle position with classical probabilistic approa…
Multifaceted phase ordering kinetics of an antiferromagnetic spin-1 condensate
Joanna Pietraszewicz, Aleksandra Seweryn, Emilia Witkowska
We study phase domain coarsening in the long time limit after a quench of magnetic field in a quasi one-dimensional spin-1 antiferromagnetic condensate. We observe that the growth…
A semiclassical field theory that is freed of the ultraviolet catastrophe
Piotr Deuar, Joanna Pietraszewicz
A more accurate semiclassical theory for ultracold gases is derived, in which the occupation of high energy modes is dynamically constrained to the Bose-Einstein distribution. This…
