Topological phase in topological Kondo insulator: topological insulator, Haldane-like phase and Kondo breakdown
Yin Zhong, Yu Liu, Hong-Gang Luo
We have simulated a half-filled -wave periodic Anderson model with numerically exact projector quantum Monte Carlo technique, and the system is indeed located in the Haldan…
Simulating heavy fermion physics in optical lattice: Periodic Anderson model with harmonic trapping potential
Yin Zhong, Yu Liu, Hong-Gang Luo
Periodic Anderson model (PAM), where local electron orbitals interplay with itinerant electronic carriers, plays an essential role in our understanding on heavy fermion materials.…
Phase diagram of Kondo-Heisenberg model on honeycomb lattice with geometrical frustration
Huan Li, Hai-Feng Song, Yu Liu
We calculated the phase diagram of the Kondo-Heisenberg model on two-dimensional honeycomb lattice with both nearest-neighbor and next-nearest-neighbor antiferromagnetic spin excha…
Spatial interferences in the electron transport of heavy fermion materials
Shu-feng Zhang, Yu Liu, Hai-Feng Song +1
The scanning tunneling microscopy/spectroscopy and the point contact spectroscopy represent one of the major progresses in recent heavy fermion research. Both have revealed importa…
Charge dynamics of the antiferromagnetically ordered Mott insulator
X. J. Han, Y. Liu, Z. Y. Liu +5
We study the charge dynamics of the half-filled Hubbard model on the square lattice at zero temperature. We employ a slave-fermion formulation in which the charge degrees of freedo…
