Solitons in Trapped Bose-Einstein condensates in one-dimensional optical lattices
F. Hebert, G. G. Batrouni, R. T. Scalettar
We use Quantum Monte Carlo simulations to show the presence and study the properties of solitons in the one dimensional soft-core bosonic Hubbard model with near neighbor interacti…
Ground state and finite temperature signatures of quantum phase transitions in the half-filled Hubbard model on a honeycomb lattice
Thereza Paiva, R. T. Scalettar, W. Zheng +2
We investigate ground state and finite temperature properties of the half-filled Hubbard model on a honeycomb lattice using quantum monte carlo and series expansion techniques. Unl…
Reentrant Disordering of Colloidal Molecular Crystals on 2D Periodic Substrates
M. Mikulis, C. J. Olson Reichhardt, C. Reichhardt +2
We study colloidal ordering and disordering on two-dimensional periodic substrates where the number of colloids per substrate minima is two or three. The colloids form dimer or tri…
Critical temperature for the two-dimensional attractive Hubbard Model
Thereza Paiva, Raimundo R. dos Santos, R. T. Scalettar +1
The critical temperature for the attractive Hubbard model on a square lattice is determined from the analysis of two independent quantities, the helicity modulus, , and the pa…
Domain regime in two-dimensional disordered vortex matter
Mahesh Chandran, R. T. Scalettar, G. T. Zimanyi
A detailed numerical study of the real space configuration of vortices in disordered superconductors using 2D London-Langevin model is presented. The magnetic field is varied b…
