One-dimensional Fermi polaron in a combined harmonic and periodic potential
Elmer V. H. Doggen, Anna Korolyuk, Päivi Törmä +1
We study an impurity in a one-dimensional potential consisting of a harmonic and a periodic part using both the time-evolving block decimation (TEBD) algorithm and a variational an…
Collective excitations of a trapped Fermi gas at finite temperature
A. Korolyuk, J. J. Kinnunen, P. Törmä
We study collective excitations of a trapped Fermi gas at finite temperature using the Bogoliubov-deGennes mean-field theory in conjunction with the generalized random phase approx…
Density response of a trapped Fermi gas: a crossover from the pair vibration mode to the Goldstone mode
A. Korolyuk, J. J. Kinnunen, P. Törmä
We consider the density response of a trapped two-component Fermi gas. Combining the Bogoliubov-deGennes method with the random phase approximation allows the study of both collect…
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…
