Metal-Insulator transition in strained Graphene: A quantum Monte carlo study
Lufeng Zhang, Chi Ma, Tianxing Ma
Motivated by the possibility of a strain tuning effect on electronic properties of graphene, the semimetal-Mott insulator transition process on the uniaxial honeycomb lattice is nu…
Intermediate Phase in Interacting Dirac Fermions with Staggered Potential
Jingyao Wang, Lufeng Zhang, Runyu Ma +3
By performing exact quantum Monte Carlo simulations of a model of interacting Dirac Fermions with staggered potential, we reveal a novel intermediate phase where the electronic cor…
Determinant Quantum Monte Carlo Study of Exhaustion in the Periodic Anderson Model
Lufeng Zhang, Tianxing Ma, Natanael C. Costa +2
The Kondo and Periodic Anderson models describe many of the qualitative features of local moments coupled to a conduction band, and thereby the physics of materials such as the hea…
Antiferromagnetically ordered Mott insulator and superconductivity in twisted bilayer graphene: A quantum Monte carlo study
Tongyun Huang, Lufeng Zhang, Tianxing Ma
Using exact quantum Monte Carlo method, we examine the recent novel electronic states seen in magic-angle graphene superlattices. From the Hubbard model on a double-layer honeycomb…
