Absence of metallicity in K-doped picene: Importance of electronic correlations
Andreas Ruff, Michael Sing, Ralph Claessen +4
Potassium-doped picene (Kpicene) has recently been reported to be a superconductor at with critical temperatures up to 18 K. Here we study the electronic structure of K-d…
Mott correlated states in the underdoped two-dimensional Hubbard model: variational Monte Carlo versus a dynamical cluster approximation
Luca F. Tocchio, Hunpyo Lee, Harald O. Jeschke +2
We investigate the properties of the frustrated underdoped Hubbard model on the square lattice using two complementary approaches, the dynamical cluster extension of dynamical mean…
A General Mechanism for Orbital Selective Phase Transitions
Yu-Zhong Zhang, Hunpyo Lee, Hai-Qing Lin +3
Based on the analysis of a two-orbital Hubbard model within a mean-field approach, we propose a mechanism for an orbital selective phase transition (OSPT) where coexistence of loca…
