Repulsively-bound exciton-biexciton states in high-spin fermions in optical lattices
A. Argüelles, L. Santos
We show that the interplay between spin-changing collisions and quadratic Zeeman coupling provides a novel mechanism for the formation of repulsively bound composites in high-spin…

Correlation dynamics of strongly-correlated bosons in time-dependent optical lattices
Karen Rodriguez, Arturo Argüelles, Luis Santos
We analyze by means of Matrix-Product-State simulations the correlation dynamics of strongly-correlated superfluid Bose gases in one-dimensional time-dependent optical lattices. We…
