Theory of anisotropic superexchange in insulating cuprates.

Spin-orbit corrections to superexchange are calculated using the method of Moriya [T. Moriya, Phys. Rev. 120 91, (1960)] for two of the insulating parent compounds of the cuprate superconductors: (1) La2−xNdxCuO4 where the CuO6 octahedra forming each Cu-O layer are tilted in staggered fashion about an axis which depends on x and temperature; and (2) YBa2Cu3O6+x (x ∼ 0.4) where the Cu-O layers f...

A Class of N-body Problems With Nearest And Next-to-Nearest Neighbour Interactions

We obtain the exact ground state and a part of the excitation spectrum in one dimension on a line and the exact ground state on a circle in the case where N particles are interacting via nearest and nextto-nearest neighbour interactions. Further, using the exact ground state, we establish a mapping between these N -body problems and the short-range Dyson models introduced recently to model inte...

Effect of the next-nearest neighbor hopping on the stability and band structure of the incommensurate phases in the cuprates

Using a spin-rotation invariant version of the slave-boson approach we investigate the relative stability and band structure of various incommensurate phases in the cuprates. Our findings obtained in the Hubbard model with next-nearest neighbor hopping −t/t ≃ 0.15, as appropriate for the La2−xSrxCuO4 family, support the formation of diagonal (vertical) stripe phases in the doping regime x = 1/1...

Equilibrium and dynamical properties of the axial next-nearest-neighbor ising chain at the multiphase point

We study the equilibrium and dynamical properties of the axial next-nearest-neighbor Ising chain at the multiphase point. An interesting property of the system is the macroscopic degeneracy of the ground state leading to finite zero-temperature entropy. In our equilibrium study we consider the effect of softening the spins. We show that the degeneracy of the ground state is lifted and there is ...
