Supersymmetric approach to the infinite U Hubbard Model
We present a preliminary discussion on the use of 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 to treat the physics of the infinite U Hubbard model. By looking for solutions to the Hamiltonian in which the spins can exist as both condensed ordered moments and as mobile charged carr...
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 کاملCompressibility of the Two-Dimensional Infinite-U Hubbard Model
We study the interactions between the coherent quasiparticles and the incoherent Mott-Hubbard excitations and their effects on the low-energy properties in the U ` Hubbard model. Within the framework of a systematic large-N expansion, these effects first occur in the next-to-leading order in 1 N . We calculate the scattering phase shift and the free energy, and determine the quasiparticle weigh...
متن کاملLinked-cluster expansion for the Green's function of the infinite-U Hubbard model.
We implement a highly efficient strong-coupling expansion for the Green's function of the Hubbard model. In the limit of extreme correlations, where the onsite interaction is infinite, the evaluation of diagrams simplifies dramatically enabling us to carry out the expansion to the eighth order in powers of the hopping amplitude. We compute the finite-temperature Green's function analytically in...
متن کاملOne-dimensional large-U Hubbard model: An analytical approach.
The basic properties of the Hubbard chain are systematically studied in the large-U regime by a path-integral formalism. The bare electron (hole) is shown to be a composite particle of two basic excitations, holon and spinon, together with the nonlocal string fields. Both holon and spinon are described by fermions with gapless spectra. Based on these quasiparticles, various correlation function...
