Population eigenstates of the SU(d) spin-exchange model for high-spin fermions in optical lattices
Hubert Dunikowski, Emilia Witkowska
We investigate the spin exchange model describing ultra-cold fermionic atoms with spin in a one-dimensional optical lattice. The model emerges from the Fe…
Degeneracy-governed spin squeezing in high-spin Fermi-Hubbard systems weakly coupled to light
Hubert Dunikowski, Emilia Witkowska
High-spin alkaline-earth fermions in optical lattices are promising platforms for spin squeezing beyond the spin-1/2 paradigm. We show that spin-squeezing dynamics is qualitatively…
Magnetization-induced reordering of ground states phase diagram in a two-component Bose-Hubbard model
Oskar Stachowiak, Hubert Dunikowski, Emilia Witkowska
We investigate the influence of non-zero magnetization on the ground-state phase diagram of the two-component Bose-Hubbard model. Employing a mean-field theoretical framework, both…
Effective light-induced Hamiltonian for atoms with large nuclear spin
Domantas Burba, Hubert Dunikowski, Martin Robert-de-Saint-Vincent +2
Ultra-cold fermionic atoms, having two valence electrons, exhibit a distinctive internal state structure, wherein the nuclear spin becomes decoupled from the electronic degrees of…
