The strong correlation effects on topological insulator are studied in a two-sublattice system with an onsite single-particle energy difference between two sublattices. At = 0, increasing the onsi...
Electronic Correlation effects in superconducting picene from ab-initio calculations
Electronic Correlation effects superconducting picene
2010/11/23
We show, by means of ab-initio calculations, that electron-electron correlations play an impor-
tant role in potassium-doped picene (Kx-picene), recently characterized as a superconductor with Tc = 1...

Correlation Effects Quantum Spin Hall Insulators Quantum Monte Carlo Study
2010/11/25
We consider the Kane-Mele model with spin-orbit coupling supplemented by a Hubbard U term.
On the basis of projective auxiliary eld quantum Monte Carlo simulations on lattice sizes up to 12 12, ...
Spin Correlation Effects in Top Quark Pair Production at the LHC
Large Hadron Collider Spin Correlation Top Quark Pair Production
2010/3/15
At a 14 TeV proton-proton collider, the Large Hadron Collider (LHC), we show that top quark pair production is dominated at low invariant mass by the fusion of two like-helicity gluons, producing top ...
Exchange-Correlation Effects in the Impurity-Limited Mobility of GaAs Quantum Wires
Exchange-Correlation Effects GaAs Quantum Wires Impurity-Limited Mobility
2010/4/16
We study the many-body effects described by the local-field corrections on the mobility of quasi-one dimensional electron systems. The low temperature mobility due to remote-impurity doping and interf...
