Collective spin 1 singlet phase in high pressure oxygen
Y. Crespo, M. Fabrizio, S. Scandolo +1
Oxygen, one of the most common and important elements in nature, has an exceedingly well explored phase diagram under pressure, up and beyond 100 GPa. At low temperatures, the low…
Spectroscopic fingerprints of a surface Mott-Hubbard insulator: the case of SiC(0001)
G. Santoro, S. Scandolo, E. Tosatti
We discuss the spectroscopic fingerprints that a surface Mott-Hubbard insulator should show at the intra-atomic level. The test case considered is that of the Si-terminated SiC(000…
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…
