Unconventional quantum phases of lattice bosonic mixtures
P. Buonsante, S. M. Giampaolo, F. Illuminati +2
We consider strongly interacting boson-boson mixtures on one-dimensional lattices and, by adopting a qualitative mean-field approach, investigate their quantum phases as the inters…
Charge dynamics of doped holes in high Tc cuprates - A clue from optical conductivity
A. S. Mishchenko, N. Nagaosa, Z. -X. Shen +6
The charge dynamics in weakly hole doped high temperature superconductors is studied in terms of the accurate numerical solution to a model of a single hole interacting with a quan…
Density functional study of oxygen vacancies at the SnO2 surface and subsurface sites
F. Trani, M. Causa', D. Ninno +2
Oxygen vacancies at the SnO2(110) and (101) surface and subsurface sites have been studied in the framework of density functional theory by using both all-electron Gaussian and pse…
Theory of ground state factorization in quantum cooperative systems
S. M. Giampaolo, G. Adesso, F. Illuminati
We introduce a general analytic approach to the study of factorization points and factorized ground states in quantum cooperative systems. The method allows to determine rigorously…
Indirect electric field doping of the CuO2 planes of the cuprate NdBa2Cu3O7 superconductor
M. Salluzzo, G. Ghiringhelli, J. C. Cezar +4
The mechanism of field-effect doping in the "123" high critical temperature superconductors (HTS) has been investigated by x-ray absorption spectroscopy in the presence of an elect…
