A correlated Anderson insulator on the honeycomb lattice

Tianxing Ma, Lufeng Zhang, Chia-Chen Chang +2

We study the effect of disorder on the semimetal -- Mott insulator transition in the half-filled repulsive Hubbard model on a honeycomb lattice, a system that features vanishing de…

Revealing extremely low energy amplitude modes in the charge-density-wave compound LaAgSb

R. Y. Chen, S. J. Zhang, M. Y. Zhang +2

The layered lanthanum silver antimonide LaAgSb was known to experience two charge density (CDW) phase transitions, which were proposed recently to be closely related to the new…

Orbital-differentiated coherence-incoherence crossover identified by photoemission spectroscopy in LiFeAs

H. Miao, Z. P. Yin, S. F. Wu +12

In the iron-based superconductors (FeSCs), orbital differentiation is an important phenomenon, whereby correlations stronger on the dxy orbital than on the dxz/yz orbital yield qua…

Orbital-selective Mott phase of Cu-substituted iron-based Superconductors

Yang Liu, Yang-Yang Zhao, Yun Song

We study the phase transition in Cu-substituted iron-based superconductors with a new developed real-space Green's function method. We find that Cu substitution has strong effect o…
