Vortex dynamics and Hall conductivity of hard-core bosons
Magnetotransport of hard-core bosons is studied using an XXZ quantum spin model representation, appropriately gauged on the torus to allow for an external magnetic field. We find strong lattice effects near half filling. An effective quantum mechanical description of the vortex degrees of freedom is derived. Using semiclassical and numerical analysis we compute the vortex-hopping energy tV, whi...
متن کاملDo Hard-core Bosons Exhibit Quantum Hall Effect?
We motivate the study of hard-core bosons in an external magnetic eld by describing anyons either as fermions or hard-core bosons with gauge-ux attached to them. We brieey review earlier attempts to address this problem. We show why quantum Hall eeect (QHE) for hard-core bosons can occur in the thermodynamic limit and use a variational trial wavefunction approach to identify the lling factors w...
متن کاملFractional quantum Hall effect of hard-core bosons in topological flat bands.
Recent proposals of topological flat band models have provided a new route to realize the fractional quantum Hall effect without Landau levels. We study hard-core bosons with short-range interactions in two representative topological flat band models, one of which is the well-known Haldane model (but with different parameters). We demonstrate that fractional quantum Hall states emerge with sign...
متن کاملDynamical Quasicondensation of Hard-Core Bosons at Finite Momenta.
Long-range order in quantum many-body systems is usually associated with equilibrium situations. Here, we experimentally investigate the quasicondensation of strongly interacting bosons at finite momenta in a far-from-equilibrium case. We prepare an inhomogeneous initial state consisting of one-dimensional Mott insulators in the center of otherwise empty one-dimensional chains in an optical lat...
متن کاملQuantum phase transitions of hard-core bosons in background potentials.
We study the zero temperature phase diagram of hard-core bosons in two dimensions subjected to three types of background potentials: staggered, uniform, and random. In all three cases there is a quantum phase transition from a superfluid (at small potential) to a normal phase (at large potential), but with different universality classes. As expected, the staggered case belongs to the XY univers...
