Competitive algorithms for calculating the ground state properties of Bose-Fermi mixtures
Tomasz Świsłocki, Krzysztof Gawryluk, Mirosław Brewczyk +1
In this work we define, analyze, and compare different numerical schemes that can be used to study the ground state properties of Bose-Fermi systems, such as mixtures of different…
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…
Quantum fluctuation effects on the quench dynamics of thermal quasicondensates
Tomasz Świsłocki, Piotr Deuar
We study the influence of quantum fluctuations on the phase, density, and pair correlations in a trapped quasicondensate after a quench of the interaction strength. To do so, we de…
Optimization as a route towards observing the Einstein-de Haas effect in a rubidium condensate
Tomasz Świsłocki, Mariusz Gajda, Mirosław Brewczyk
The main obstacle in experimental realization of the Einstein-de Haas effect in a Bose-Einstein condensate is necessity of a very precise control of the extremely small (of the ord…
Resonant dynamics of chromium condensates
Tomasz Świsłocki, Jarosław H. Bauer, Mariusz Gajda +1
We numerically study the dynamics of a spinor chromium condensate in low magnetic fields. We show that the condensate evolution has a resonant character revealing rich structure of…
Dynamics of the modified Kibble-Żurek mechanism in antiferromagnetic spin-1 condensates
Emilia Witkowska, Jacek Dziarmaga, Tomasz Świsłocki +1
We investigate the dynamics and outcome of a quantum phase transition from an antiferromagnetic to phase separated ground state in a spin-1 Bose-Einstein condensate of ultracold at…
Double universality of a quantum phase transition in spinor condensates: the Kibble-Żurek mechanism and a conservation law
Tomasz Swislocki, Emilia Witkowska, Jacek Dziarmaga +1
We consider a phase transition from antiferromagnetic to phase separated ground state in a spin-1 Bose-Einstein condensate of ultracold atoms. We demonstrate the occurrence of two…
Controlled spin domain creation by phase separation
Tomasz Swislocki, Michal Matuszewski
We demonstrate a method of controlled creation of spin domains in spin-1 antiferromagnetic Bose-Einstein condensates. The method exploits the phenomenon of phase separation of spin…
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…

Tomasz Świsłocki, Tomasz Sowiński, Mirosław Brewczyk +1
We study a square plaquette of four optical microtraps containing ultracold Rb atoms in F=1 hyperfine state. In a presence of external resonant magnetic field the dipolar in…

Tomasz Świsłocki, Mirosław Brewczyk, Mariusz Gajda +1
We consider a spinor condensate of Rb atoms in F=1 hyperfine state confined in an optical dipole trap. Putting initially all atoms in component we find that the syst…
