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…
Spin-asymmetric Josephson effect
M. O. J. Heikkinen, F. Massel, J. Kajala +3
The Josephson effect is a manifestation of the macroscopic phase coherence of superconductors and superfluids. We propose that with ultracold Fermi gases one can realise a spin-asy…
Resonant scattering effect in spectroscopies of interacting atomic gases
M. J. Leskinen, J. Kajala, J. J. Kinnunen
We consider spectroscopies of strongly interacting atomic gases, and we propose a model for describing the coupling between quasiparticles and gapless phonon-like modes. Our model…
Bakhtiari, Leskinen and Torma Reply
M. Reza Bakhtiari, M. J. Leskinen, P. Törmä
This is a Reply to: Comment on "Spectral Signatures of the Fulde-Ferrell-Larkin-Ovchinnikov Order Parameter in One-Dimensional Optical Lattices" R. A. Molina J. Dukelksy, and P. Sc…
Hopping modulation in a one-dimensional Fermi-Hubbard Hamiltonian
F. Massel, M. J. Leskinen, P. Torma
We consider a strongly repulsive two-component Fermi gas in a one-dimensional (1D) optical lattice described in terms of a Hubbard Hamiltonian. We analyze the response of the syste…
Quasiparticles, coherence and nonlinearity: exact simulations of RF-spectroscopy of strongly interacting one-dimensional Fermi gases
M. J. Leskinen, V. Apaja, J. Kajala +1
We consider RF-spectroscopy of ultracold Fermi gases by exact simulations of the many-body state and the coherent dynamics in one dimension. Deviations from the linear response sum…
