HOLONS WITH SPINON CLOUD IN THE DOPED RVB STATE

Abstract

The effect of interactions between holons and spinons in doped resonating valence bond states is investigated. In particular, we focus on those interactions through which a holon emits or absorbs spinons, and we study the influence of these interactions on the effective mass of a holon along the slave boson treatment in the mean field approximation. Our result asserts that the spinon cloud scarcely affects the effective mass of a holon in both s- and d-wave states.

On the relation between the boson-fermion model and RVB state

Eugeny Kochetov, Marcin Mierzejewski

We show that the resonating valence bond (RVB) state of the t-J Hamiltonian can be described within an effective boson-fermion model. We derive a boson-fermion Hamiltonian which describes the lowest order coupling between holons and spinon waves. The RVB order parameter determines a hybridization between the both types of excitations. The effective Hamiltonian is investigated within the lowest order self-consistent conserving diagrammatic approximation. We compare our approach with the phenomenological boson--fermion model (BFM) that is believed to describe the pseudogap phase.

Evaluation of the effective holon-holon interaction by the slave-fermion method

Yongjun Liu, Jinming Dong, Chang-De Gong

The effective holon-holon interaction by exchanging the spinons in the resonating-valence bond model is derived by the slave-fermion method. The authors found that the interaction is attractive for the holon Cooper pair. Complexity due to Bose condensation of the spinons at T=0 has been discussed.

Nonmagnetic impurity in the spin-gap state

Naoto Nagaosa, Tai Kai Ng

The effects of nonmagnetic strong scatterers (unitary limit) on magnetic and transport properties are studied for resonating-valence-bond states in both the slave-boson and slave-fermion mean-field theories with the gap for the triplet excitations. In the d-wave pairing state of the slave-boson mean-field theory in two dimensions, there is no true gap for spinons, but the Anderson localization occurs, which leads to the local moment when the repulsive interaction is taken into account. In the slave-fermion mean-field theory, local moments are found bound to nonmagnetic impurities as a result of (staggered) gauge interaction. However, in both theories, localization of spinon does not appear in the resistivity, which shows the classical value for the holon.

Boson Mean Field Theory of Effective Holon-Holon Interaction in the RVB Model

Yongjun Liu, Jinming Dong, Chang-De Gong

The RVB model is investigated by a mean field theory, in which the holon is expressed by a fermion operator, and the spinon by a boson operator. The effective holon-holon interaction by exchanging the spinons is derived for . It is found that the interaction is attractive.

EFFECTIVE SPINON-SPINON AND HOLON-HOLON INTERACTIONS IN RVB MODELS OF HIGH-T c SUPERCONDUCTIVITY

Nguyen Van Hieu

The interaction between the bosonic excitations as well as between the fermionic ones in the RVB systems with the (extended) Hubbard Hamiltonian were studied by means of the slave boson technique and the perturbation theory. The corresponding effective Hamiltonians have been found. It was shown, in particular, that in the RVB system with two interpenetrating sublattices there exists the effective attraction between two holons of different kinds as well as between two spinions of different kinds in the singlet state.

Effective holon-holon interaction in the resonating-valence-bond state

Y. R. Wang

The effective holon-holon interaction mediated by the spinon background is derived in the framework of the resonating-valence-bond model. The interaction is present only after the spinons undergo a transition to a spin superfluid state and is attractive for the holon Cooper pairs. The latter property of the holon-holon interaction gives further support to the conjecture that the two-dimensional Hubbard model by itself in the large-U limit could lead to superconductivity.
