Few interacting fermions in one-dimensional harmonic trap
Tomasz Sowiński, Tobias Grass, Omjyoti Dutta +1
We study spin-1/2 fermions, interacting via a two-body contact potential, in a one-dimensional harmonic trap. Applying exact diagonalization, we investigate their behavior at finit…
Criticality in the Bose-Hubbard model with three-body repulsion
Tomasz Sowiński, Ravindra W. Chhajlany, Omjyoti Dutta +2
We study the attractive Bose-Hubbard model with a tunable, on-site three-body constraint. It is shown that the critical behavior of the system undergoing a phase transition from pa…
Spin dynamics of two bosons in an optical lattice site: a role of anharmonicity and anisotropy of the trapping potential
Joanna Pietraszewicz, Tomasz Sowiński, Mirosław Brewczyk +2
We study a spin dynamics of two magnetic Chromium atoms trapped in a single site of a deep optical lattice in a resonant magnetic field. Dipole-dipole interactions couple spin degr…
