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…
Induced interactions and the superfluid transition temperature in a three-component Fermi gas
J. -P. Martikainen, J. J. Kinnunen, P. Torma +1
We study many-body contributions to the effective interaction between fermions in a three-component Fermi mixture. We find that effective interactions induced by the third componen…
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…
Vacuum Rabi splitting and strong coupling dynamics for surface plasmon polaritons and Rhodamine 6G molecules
T. K. Hakala, J. J. Toppari, A. Kuzyk +4
We report on strong coupling between surface plasmon polaritons (SPP) and Rhodamine 6G (R6G) molecules, with double vacuum Rabi splitting energies up to 230 and 110 meV. In additio…
Dynamics of quantum phase transitions in Dicke and Lipkin-Meshkov-Glick models
A. P. Itin, P. Törmä
We consider dynamics of Dicke models, with and without counterrotating terms, under slow variations of parameters which drive the system through a quantum phase transition. The mod…
