Supersolid phases of hardcore bosons on the square lattice: Correlated hopping, next-nearest neighbor hopping and frustration
F. Mila, J. Dorier, K. P. Schmidt
We discuss the appearance of supersolid phases for interacting hardcore bosons on the square lattice when, in addition to the standard nearest neighbor hopping and repulsion, corre…
Magnetization plateaux in an extended Shastry-Sutherland model
K. P. Schmidt, J. Dorier, F. Mila
We study an extended two-dimensional Shastry-Sutherland model in a magnetic field where besides the usual Heisenberg exchanges of the Shastry-Sutherland model two additional SU(2)…
Theory of magnetization plateaux in the Shastry-Sutherland model
J. Dorier, K. P. Schmidt, F. Mila
Using perturbative continuous unitary transformations, we determine the long-range interactions between triplets in the Shastry-Sutherland model, and we show that an unexpected str…
Solids and supersolids of three-body interacting polar molecules in an optical lattice
Kai P. Schmidt, Julien Dorier, Andreas Laeuchli
We study the physics of cold polar molecules loaded into an optical lattice in the regime of strong three-body interactions, as put forward recently by Büchler [Nature Phys. 3, 726…
