Haldane phase in one-dimensional topological Kondo insulators

We investigate the ground-state properties of a recently proposed model for a topological Kondo insulator in one dimension (i.e., the p-wave Kondo-Heisenberg lattice model) by means of the… Expand

Spectral gap induced by structural corrugation in armchair graphene nanoribbons

- S. Costamagna, O. Hernandez, A. Dobry
- Physics
- 7 January 2010

AGNRs can be either metallic or semiconductor, depending on their width 8 . However, experiments suggest that AGNR are always insulators with a gap that scale with the inverse of its width 9 . The… Expand

- Materials Science, Physics
- 21 July 2014

Quantum thermal transport in armchair and zigzag graphene nanoribbons is investigated in the presence of single atomic vacancies and subject to different boundary conditions. We start with a full… Expand

Monte Carlo simulation of the role of defects as a melting mechanism

We study in this paper the melting transition of a crystal of a fcc structure with the Lennard-Jones potential, by using isobaric-isothermal Monte Carlo simulations. Local and collective updates are… Expand
