Monte Carlo studies of quantum and classical annealing on a double-well
Lorenzo Stella, Giuseppe E. Santoro, Erio Tosatti
We present results for a variety of Monte Carlo annealing approaches, both classical and quantum, benchmarked against one another for the textbook optimization exercise of a simple…
Strain effects at solid surfaces near the melting point
U. Tartaglino, E. Tosatti
We investigate the effects of strain on a crystal surface close to the bulk melting temperature T_m, where surface melting usually sets in. Strain lowers the bulk melting point, so…
Disproportionation Phenomena on Free and Strained Sn/Ge(111) and Sn/Si(111) Surfaces
G. Ballabio, G. Profeta, S. de Gironcoli +3
Distortions of the Sn/Ge(111) and Sn/Si(111) surfaces are shown to reflect a disproportionation of an integer pseudocharge, , related to the surface band oc…
Charge density waves and surface Mott insulators for adlayer structures on semiconductors: extended Hubbard modeling
Giuseppe Santoro, Sandro Scandolo, Erio Tosatti
Motivated by the recent experimental evidence of commensurate surface charge density waves (CDW) in Pb/Ge(111) and Sn/Ge(111) sqrt{3}-adlayer structures, as well as by the insulati…
Metallic charge density waves and surface Mott insulators for adlayer structures on semiconductors: extended Hubbard modeling
G. Santoro, S. Sorella, F. Becca +2
Motivated by the recent experimental evidence of commensurate surface CDW in Pb/Ge(111) and Sn/Ge(111) -adlayer structures, as well as by the insulating states found on K…
