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…
