Accurate Six-Band Nearest-Neighbor Tight-Binding Model for the Ï•-Bands of Bulk Graphene and Graphene Nanoribbons
Accurate modeling of the S-bands of armchair graphene nanoribbons (AGNRs) requires correctly reproducing asymmetries in the bulk graphene bands as well as providing a realistic model for hydrogen passivation of the edge atoms. The commonly used single-p z orbital approach fails on both these counts. To overcome these failures we introduce a nearest-neighbor, three orbital per atom p/d tight-bin...
متن کاملQuantum fluctuations in the axial next-nearest-neighbor ising model.
We obtain the axial next-nearest-neighbor Ising model from a Heisenberg model with large single-ion anisotropy energy, D, as might be relevant for helical spin systems. We treat quantum fluctuations to lowest order in 1/S at zero temperature within an expansion in J/D, where J is an exchange energy. The transition from the state with periodicity p=4 to the uniform state (p=∞) occurs via a seque...
متن کاملNext-Nearest-Neighbor Hopping in the Falicov–Kimball Model
Results of Monte Carlo simulations for the spinless Falicov–Kimball model with the next-nearest-neighbor hopping are presented. We find the critical value of the next-nearest-neighbor hopping integral, below which the low temperature configuration of the localized particles is the same as in the presence of only the nearest-neighbor hopping. Beyond this critical value the localized particles fo...

متن کاملThe fully frustrated XY model with next nearest neighbor interaction
We introduce a fully frustrated XY model with nearest neighbor (nn) and next nearest neighbor (nnn) couplings which can be realized in Josephson junction arrays. We study the phase diagram for 0 ≤ x ≤ 1 (x is the ratio between nnn and nn couplings). When x < 1/ √ 2 an Ising and a BerezinskiiKosterlitz-Thouless transitions are present. Both critical temperatures decrease with increasing x. For x...
