The flat band of edge states that occur in the simple tight-binding lattice model graphene with a zigzag have long been conjectured to take up ferromagnetic configuration. In this work, we prove that, for large class interaction Hamiltonians can be added model, and at first order perturbation theory, degeneracy is resolved such way ground state maximal, spin j = N/2 representation symmetry, whe...

Abstract Zigzag planting method technology was an alternative to increase plant population without affecting growth and development. The purpose of this study determine the productivity corn with different methods, such as zigzag linear applied by farmers on acid dry land in Lampung area. research conducted at Natar Experimental Station Negara Ratu Village, District, South Regency, Indonesia fr...

dft calculations were applied to evaluate the electronic and magnetic properties of zigzag bc2nnanotubes based on the 13c, 15n, and 11b nmr parameters and natural charge analysis. weconsidered three types of zigzag nanotubes, zz-1, zz-2, and zz-3 (n, 0) with n = 8, 12, and 14. theobtained results indicated the divisions of the electrostatic environments around c nuclei into a fewlayers, consist...

stabilities and quantum molecular descriptors of cyclophoshphamide (an anticancer drug)-functionalized (8,0) zigzag and (4,4) armchair carbon nanotubes (cnts) complexes in water were studied using density functional theory (dft) calculations. two attachments namely the sidewall- and tip-attachments are considered for the model constructions. calculations of the total electronic energy (et) and ...

Le processus de ZigZag est une variante du télégraphe avec des intensités retournement dépendant la position. Nous obtenons caractérisation spectre en norme L2 générateur zigzag unidimensionnel, dans le cas où distribution marginale stationnaire sur R unimodale, fréquence rééchantillonnage nulle. conditions suffisantes pour un théorème d’isomorphisme spectral, identifiant à celui semi-groupe Ma...
