Phase-Locking of Vortex Lattices Interacting with Periodic Pinning
Charles Reichhardt, Richard T. Scalettar, Gergely T. Zimanyi +1
We examine Shapiro steps for vortex lattices interacting with periodic pinning arrays driven by AC and DC currents. The vortex flow occurs by the motion of the interstitial vortice…
The Effect of Splayed Pins on Vortex Creep and Critical Currents
C. J. Olson, R. T. Scalettar, G. T. Zimanyi
We study the effects of splayed columnar pins on the vortex motion using realistic London Langevin simulations. At low currents vortex creep is strongly suppressed, whereas the cri…
Phase separation in supersolids
G. G. Batrouni, R. T. Scalettar
We study quantum phase transitions in the ground state of the two dimensional hard-core boson Hubbard Hamiltonian. Recent work on this and related models has suggested ``supersolid…
Conducting phase in the two-dimensional disordered Hubbard model
P. J. H. Denteneer, R. T. Scalettar, N. Trivedi
We study the temperature-dependent conductivity and spin susceptibility of the two-dimensional disordered Hubbard model. Calculations of the current-current correlati…
Auxiliary-field Monte Carlo for Quantum Spin and Boson Systems
M. Ulmke, R. T. Scalettar
We describe a new algorithm for the numerical simulation of quantum spin and boson systems. The method is based on the Trotter decomposition in imaginary time and a decoupling by a…
Similarities between the Hubbard and Periodic Anderson Models at Finite Temperatures
K. Held, C. Huscroft, R. T. Scalettar +1
The single band Hubbard and the two band Periodic Anderson Hamiltonians have traditionally been applied to rather different physical problems - the Mott transition and itinerant ma…
