Making two dysprosium atoms rotate - Einstein-de Haas effect revisited
Wojciech Górecki, Kazimierz Rzążewski
We present a numerical study of the behaviour of two magnetic dipolar atoms trapped in a harmonic potential and exhibiting the standard Einstein-de Haas effect while subject to a t…
Condensate losses and oscillations induced by Rydberg atoms
Tomasz Karpiuk, Mirosław Brewczyk, Kazimierz Rzążewski +5
We numerically analyze the impact of a single Rydberg electron onto a Bose-Einstein condensate. Both and Rydberg states are studied. The radial size of and state…
Anomalous oscillations of dark solitons in trapped dipolar condensates
T. Bland, K. Pawlowski, M. J. Edmonds +2
Thanks to their immense purity and controllability, dipolar Bose-Einstein condensates are an exemplar for studying fundamental non-local nonlinear physics. Here we show that a fami…
Thermal solitons as revealed by static structure factor
Krzysztof Gawryluk, Mirosław Brewczyk, Kazimierz Rzążewski
We study, within a framework of the classical fields approximation, the static structure factor of a weakly interacting Bose gas at thermal equilibrium. As in a recent experiment (…
Diffusion in a system of a few distinguishable fermions in a one-dimensional double-well potential
Tomasz Sowiński, Mariusz Gajda, Kazimierz Rzążewski
Dynamical properties of a few ultra-cold fermions confined in a double-well potential is studied. We show that the dynamics, which is governed by single-particle tunnelings for van…
Two dipolar atoms in a harmonic trap
Rafał Ołdziejewski, Wojciech Górecki, Kazimierz Rzążewski
Two identical dipolar atoms moving in a harmonic trap without an external magnetic field are investigated. Using the algebra of angular momentum a semi - analytical solutions are f…
