چکیده
We develop a supersymmetric representation of the Hubbard operators which unifies the Slave Boson and Slave Fermion representations, allowing a second-quantized treatment of Hubbard operators with both symmetric and anti-symmetric character. We provide a simple example of the application of this method to the atomic limit of the Hubbard model and discuss its more general application to the infinite U Anderson model and the t − J model.

Supersymmetric Hubbard operators
We develop a supersymmetric representation of the Hubbard operator which unifies the slave boson and slave fermion representations into a single U(1)× SU(1|1) gauge theory, a group with larger symmetry than the product of two U(1) gauge groups. These representations of the Hubbard operator can be used to incorporate strong Hund’s interactions in multi-electron atoms as a constraint. We show how...
متن کاملSpectrum of Low-lying Excitations in a Supersymmetric Extended Hubbard Model 1
We continue the study of the u(2j2)-supersymmetric extension of the Hubbard model in one dimension. We determine the excitation spectrum at zero temperature even in the sectors where the ground states are u(2j2)-descendants of Bethe states. The ex-citations include spinons, holons, electrons, localons (local electrons pairs, moving coherently through the lattice) and their bound states. The spe...
متن کاملA supersymmetric mean - field approach to the infinite - U Hubbard model
A supersymmetric mean-field approach to the infinite-U Hubbard model Abstract A generalized supersymmetric representation of the Hubbard operator algebra is considered. This representation is applied to the infinite-U Hub-bard model. A mean-field theory which takes into account both on-site and inter-site virtual boson-fermion transitions is developed. Unlike previous approaches , the mean-fiel...
متن کاملStructure of the Hilbert-space of the infinite-dimensional Hubbard model
An iterative procedure for the explicit construction of the nontrivial subspace of all symmetryadapted configurations with non-zero weight in the ground-state of the ∞-dimensional Hubbard model is developed on the basis of a symmetrized representation of the transition operators on a sequence of Bethe-Lattices of finite depth. The relation ship between these operators and the well known mapping...
متن کاملروش انتگرال مسیر برای مدل هابارد تک نواره
We review various ways to express the partition function of the single-band Hubard model as a path integral. The emphasis is made on the derivation of the action in the integrand of the path integral and the results obtained from this approach are discussed only briefly. Since the single-band Hubbard model is a pure fermionic model on the lattice and its Hamiltonian is a polynomial in creat...
