Coexistence of pairing gaps in three-component Fermi gases
O. H. T. Nummi, J. J. Kinnunen, P. Törmä
We study a three-component superfluid Fermi gas in a spherically symmetric harmonic trap using the Bogoliubov-deGennes method. We predict a coexistence phase in which two pairing f…
Exotic superfluid states of lattice fermions in elongated traps
D. -H. Kim, J. J. Kinnunen, J. -P. Martikainen +1
We present real-space dynamical mean-field theory calculations for attractively interacting fermions in three-dimensional lattices with elongated traps. The critical polarization i…
Probing the FFLO phase by double occupancy modulation spectroscopy
A. Korolyuk, F. Massel, P. Törmä
We propose here that for a spin-imbalanced two-component attractive Fermi gas loaded in a 1D optical lattice in presence of an harmonic confining potential, the observation of the…
Polaron-like effects in a one-dimensional optical lattice
Mikko Juhani Leskinen, Olli Heikki Tapio Nummi, Francesco Massel +1
We study a highly imbalanced Fermi gas in a one-dimensional optical lattice from the polaronic point of view. The time-evolving block decimationg algorithm is used to calculate the…
