Possible exciton bose liquid in a hard-core boson ring model.
We present a quantum Monte Carlo study of a hard-core boson model with ring-only exchanges on a square lattice, where a K1 term acts on 1×1 plaquettes and a K2 term acts on 1×2 and 2×1 plaquettes. At half-filling, the phase diagram reveals charge density wave for small K2, valence bond solid for intermediate K2, and possibly for large K2 the novel exciton Bose liquid (EBL) phase first proposed ...
متن کاملPossible realization of the exciton Bose liquid phase in a hard-core boson model with ring-only exchange interactions
We investigate a hard-core boson model with ring-only exchanges on a square lattice, where a K1 term acts on 1×1 plaquettes and aK2 term acts on 1×2 and 2×1 plaquettes, with a goal of realizing a novel exciton Bose liquid (EBL) phase first proposed by Paramekanti et al. [Phys. Rev. B 66, 054526 (2002)]. We construct Jastrow-type variational wave functions for the EBL, study their formal propert...
متن کاملRing exchange, the exciton Bose liquid, and bosonization in two dimensions
Motivated by the high-Tc cuprates, we consider a model of bosonic Cooper pairs moving on a square lattice via ring exchange. We show that this model offers a natural middle ground between a conventional antiferromagnetic Mott insulator and the fully deconfined fractionalized phase that underlies the spin-charge separation scenario for high-Tc superconductivity. We show that such ring models sus...
متن کاملExpansion dynamics in a one-dimensional hard-core boson model with three-body interactions
Using the adaptive time-dependent density matrix renormalization group method, we numerically investigate the expansion dynamics of bosons in a one-dimensional hard-core boson model with three-body interactions. It is found that the bosons expand ballistically with weak interaction, which are obtained by local density and the radius Rn. It is shown that the expansion velocity V, obtained from R...
متن کاملTwo-dimensional superfluidity and localization in the hard-core boson model: A quantum Monte Carlo study.
Quantum Monte Carlo simulations are used to investigate the twodimensional superfluid properties of the hard-core boson model, which show a strong dependence on particle density and disorder. We obtain further evidence that a half-filled clean system becomes superfluid via a finite temperature Kosterlitz-Thouless transition. The relationship between low temperature superfluid density and partic...
