Vacancy-assisted superfluid drag
Thomas G. Kiely, Chao Zhang, Erich J. Mueller
We study superfluid drag in the two-component Bose-Hubbard model with infinitely strong repulsive interactions. In this system, all transport is mediated by the motion of empty sit…

Dynamics of spin helices in the diluted one-dimensional model
Darren Pereira, Erich J. Mueller
Motivated by discrepancies between recent cold atom experiments and the associated theory, we explore the effect of immobile holes on the quantum dynamics of - spin helices i…

High temperature transport in the one dimensional mass-imbalanced Fermi-Hubbard model
Thomas G. Kiely, Erich J. Mueller
We study transport in the one-dimensional mass-imbalanced Fermi-Hubbard model at infinite temperature, focusing on the case of strong interactions. Prior theoretical and experiment…
