The Fulde-Ferrell-Larkin-Ovchinnikov state for ultracold fermions in lattice and harmonic potentials: a review
Jami J. Kinnunen, Jildou E. Baarsma, Jani-Petri Martikainen +1
We review the concepts and the present state of theoretical studies of spin-imbalanced superfluidity, in particular the elusive Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) state, in th…
Decoherence of an impurity in a one-dimensional fermionic bath with mass imbalance
A. -M. Visuri, J. J. Kinnunen, J. E. Baarsma +1
We study the transport, decoherence and dissipation of an impurity interacting with a bath of free fermions in a one-dimensional lattice. Numerical simulations are made with the ti…
Larkin-Ovchinnikov phases in two-dimensional square lattices
J. E. Baarsma, P. Törmä
We consider a two-component gas of fermions in optical lattices in the presence of a population imbalance within a mean-field theory. We study phase transitions from a normal gas o…
Superfluid phases of fermions with hybridized and orbitals
Shaoyu Yin, J. E. Baarsma, M. O. J. Heikkinen +2
We explore the superfluid phases of a two-component Fermi mixture with hybridized orbitals in optical lattices. We show that there exists a general mapping of this system to the Li…
