Pair scattering from time-modulated impurity in the Bose-Hubbard model
Neda Ahmadi, Ameneh Sheikhan, Corinna Kollath
We investigate scattering phenomena in a one-dimensional attractive Bose-Hubbard model with a time-periodically modulated impurity. We analyze both single-particle and pair (doublo…
Superconductivity in the repulsive Hubbard model on different geometries induced by density-assisted hopping
Franco T. Lisandrini, Edmond Orignac, Roberta Citro +2
We study the effect of density-assisted hopping on different dimerized lattice geometries, such as bilayers and ladder structures. We show analytically that the density-assisted ho…
Steady state diagram of interacting fermionic atoms coupled to dissipative cavities
Luisa Tolle, Ameneh Sheikhan, Thierry Giamarchi +2
We investigate fermionic atoms subjected to an optical lattice and coupled to a high finesse optical cavity with photon losses. A transverse pump beam introduces a coupling between…
From Light-Cone to Supersonic Propagation of Correlations by Competing Short- and Long-Range Couplings
Catalin-Mihai Halati, Ameneh Sheikhan, Giovanna Morigi +2
We investigate the dynamical spreading of correlations in many-body quantum systems with competing short- and global-range couplings. We monitor the non-equilibrium dynamics of the…
