Spinon-holon interactions in an anisotropic t-J chain: a comprehensive study
Jurij Smakov, A. L. Chernyshev, Steven R. White
We consider a generalization of the one-dimensional t-J model with anisotropic spin-spin interactions. We show that the anisotropy leads to an effective attractive interaction betw…
Binding of holons and spinons in the one-dimensional anisotropic t-J model
Jurij Smakov, A. L. Chernyshev, Steven R. White
We study the binding of a holon and a spinon in the one-dimensional anisotropic t-J model using a Bethe-Salpeter equation approach, exact diagonalization, and density matrix renorm…
Universal Scaling of the Conductivity at the Superfluid-Insulator Phase Transition
Jurij Smakov, Erik Sorensen
The scaling of the conductivity at the superfluid-insulator quantum phase transition in two dimensions is studied by numerical simulations of the Bose-Hubbard model. In contrast to…
Imaginary chemical potential quantum Monte Carlo for Hubbard molecules
Fei Lin, Jurij Smakov, Erik S. Sorensen +2
We generalize the imaginary chemical potential quantum Monte Carlo (QMC) method proposed by Dagotto et al. [Phys. Rev. B 41, R811 (1990)] to systems without particle-hole symmetry.…
QMC Calculation of the Electronic Binding Energy in a C60 Molecule
Fei Lin, Jurij Smakov, Erik S. Sorensen +2
Electronic energies are calculated for a Hubbard model on the molecule using projector quantum Monte Carlo (QMC). Calculations are performed to accuracy high enough to det…
Stripes, topological order, and deconfinement in a planar t-Jz model
J. Smakov, C. D. Batista, G. Ortiz
We determine the quantum phase diagram of a two-dimensional bosonic t-Jz model as a function of the lattice anisotropy gamma, using a quantum Monte Carlo loop algorithm. We show an…
