The Puzzling Stability of Monatomic Gold Wires
J. A. Torres, E. Tosatti, A. Dal Corso +4
We have examined theoretically the spontaneous thinning process of tip-suspended nanowires, and subsequently studied the structure and stability of the monatomic gold wires recentl…
Spin gap in low-dimensional Mott insulators with orbital degeneracy
L. Guidoni, G. Santoro, S. Sorella +2
We consider the exchange Hamiltonian H_ST = -J Sum_{<rr'>} (2 S_r S_r' - 1/2) (2 T_r T_r' - 1/2) describing two isotropic spin-1/2 Heisenberg antiferromagnets coupled by a quartic…
First Principles Calculations of Charge and Spin Density Waves of sqr3-Adsorbates on Semiconductors
S. Scandolo, F. Ancilotto, G. L. Chiarotti +3
We present ab-initio electronic structure results on the surface of sqr3 adsorbates. In particular, we address the issue of metal-insulator instabilities, charge-density-waves (CDW…
