Bethe-Salpeter approach to the collective-mode spectrum of a superfluid Fermi gas in a moving optical lattice

Zlatko Koinov, Petar Koynov

We have derived the Bethe-Salpeter (BS) equations for the collective-mode spectrum of a mixture of fermion atoms of two hyperfine states loaded into a moving optical lattice. The c…

Bethe-Salpeter equations for the collective modes of the $t - U - V - J$ model with d-wave pairing

Z. G. Koinov, P. Nash

The Bethe-Salpeter equations for the collective modes of a $t$ - $U$ - $V$ - $J$ model are used to analyze the resonance peak observed at $Q = (π, π)$ in neutron scattering experiments…
