Spin distillation cooling of ultracold Bose gases
Tomasz Świsłocki, Mariusz Gajda, Mirosław Brewczyk +1
We study the spin distillation of spinor gases of bosonic atoms and find two different mechanisms in Cr and Na atoms, both of which can cool effectively. The first…
Dynamic hysteresis from bistability in an antiferromagnetic spinor condensate
Tomasz Swisłocki, Andrzej Zembrzuski, Michał Matuszewski +1
We study the emergence of hysteresis during the process of quantum phase transition from an antiferromagnetic to a phase-separated state in a spin-1 Bose Einstein condensate of ult…
Non-adiabatic quantum phase transition in a trapped spinor condensate
Tomasz Świsłocki, Emilia Witkowska, Michał Matuszewski
We study the effect of an external harmonic trapping potential on an outcome of the non-adiabatic quantum phase transition from an antiferromagnetic to a phase-separated state in a…
Thermal fluctuations and quantum phase transition in antiferromagnetic Bose-Einstein condensates
Emilia Witkowska, Tomasz Świsłocki, Michał Matuszewski
We develop a method for investigating nonequilibrium dynamics of an ultracold system that is initially at thermal equilibrium. Our procedure is based on the classical fields approx…
Tunable dipolar resonances and Einstein-de Haas effect in a Rb-87 atoms condensate
Tomasz Swislocki, Tomasz Sowinski, Joanna Pietraszewicz +4
We study a spinor condensate of Rb-87 atoms in F = 1 hyperfine state confined in an optical dipole trap. Putting initially all atoms in mF = 1 component we observe a significant tr…
