Spinon-holon interactions in an anisotropic t-J chain: a comprehensive study (2007)
Smakov, Jurij, Chernyshev, A. L., White, Steven R.
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 between the spinon and...
Binding of holons and spinons in the one-dimensional anisotropic t-J model (2007)
Smakov, Jurij, Chernyshev, A. L., White, Steven R.
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 renormalization group...
Universal Scaling of the Conductivity at the Superfluid-Insulator Phase Transition (2005)
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 previous studies,...
Imaginary chemical potential quantum Monte Carlo for Hubbard molecules (2004)
Lin, Fei, Smakov, Jurij, Sorensen, Erik S., Kallin, Catherine, Berlinsky, A. John
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. The generalized...
QMC Calculation of the Electronic Binding Energy in a C60 Molecule (2004)
Lin, Fei, Smakov, Jurij, Sorensen, Erik S., Kallin, Catherine, Berlinsky, A. John
Electronic energies are calculated for a Hubbard model on the $C_{60}$ molecule using projector quantum Monte Carlo (QMC). Calculations are performed to accuracy high enough to determine the pair...
A quantum Monte Carlo algorithm for softcore boson systems (2003)
Smakov, Jurij, Harada, Kenji, Kawashima, Naoki
An efficient Quantum Monte Carlo algorithm for the simulation of bosonic systems on a lattice in a grand canonical ensemble is proposed. It is based on the mapping of bosonic models to the spin...
STM measurement of single spin relaxation time in superconductors (2001)
Smakov, Jurij, Martin, Ivar, Balatsky, Alexander V.
Localized spin states in conventional superconductors at low temperatures are expected to have long decoherence time due to the strong suppression of spin relaxation channels. We propose a scanning...
Josephson scanning tunneling microscopy (2000)
Smakov, Jurij, Martin, Ivar, Balatsky, Alexander V.
We propose a set of scanning tunneling microscopy experiments in which the surface of superconductor is scanned by a superconducting tip. Potential capabilities of such experimental setup are...
