Magnetic phase diagram of the Hubbard model with next-nearest-neighbour hopping
We calculate the magnetic phase diagram of the Hubbard model for a Bethe lattice with nearest neighbour (NN) hopping t1 and next nearest neighbour (NNN) hopping t2 in the limit of infinite coordination. We use the amplitude t2/t1 of the NNN hopping to tune the density of states (DOS) of the non-interacting system from a situation with particle-hole symmetry to an asymmetric one with van-Hove si...
متن کاملEFFECT OF THE NEXT-NEAREST NEIGHBOR INTERACTION ON THE ORDER-DISORDER PHASE TRANSITION
In this work, one and two-dimensional lattices are studied theoretically by a statistical mechanical approach. The nearest and next-nearest neighbor interactions are both taken into account, and the approximate thermodynamic properties of the lattices are calculated. The results of our calculations show that: (1) even though the next-nearest neighbor interaction may have an insignificant ef...
متن کاملPhase diagram of the XXZ chain with next-nearest-neighbor interactions
We calculate the quantum phase diagram of the XXZ chain with nearestneighbor (NN) J1 and next-NN exchange J2 with anisotropies ∆1 and ∆2 respectively. In particular we consider the case ∆1 = −∆2 to interpolate between the XX chain (∆i = 0) and the isotropic model with ferromagnetic J2. For ∆1 < −1, a ferromagnetic and two antiferromagnetic phases exist. For |∆i| < 1, the boundary between the di...
متن کاملUniversal Relations in the Attractive Hubbard Model with Next-Nearest Neighbor Hopping
Institute of Physics, A. Mickiewicz University Umultowska 85, 61-614 Poznań, Poland Recently a new universal relation between superfluid density ρs and σdcTc, where σdc is direct current conductivity and Tc — superconducting critical temperature, was found by Homes et al. (Nature 430, 539 (2004)). The theoretical derivation of the relation based on BCS theory is correct only qualitatively. In t...
متن کاملPhase diagram of S=1 XXZ chain with next-nearest neighbor interaction
The one dimensional S = 1 XXZ model with the next-nearest-neighbor interaction α and the anisotropy ∆ is studied by the numerical diagonalization. We study the ground state phase diagram of this model by the level spectroscopy method with the twisted boundary method, the phenomenological renormalization group method, the spin wave theory, the nonlinear σ model and the renormalization group. We ...
