Vacancy-assisted superfluid drag
The authors theoretically study superfluid drag in the two-component hard-core Bose-Hubbard model, analyzing how the hard-core constraints correlate particle motion. They derive analytical results in the jamming limit of vanishing hole density and use complementary numerical techniques to study finite hole densities in two-dimensional lattices.
