Disorder Suppression of Charge Density Waves in the Honeycomb Holstein Model
Guangchao Li, Lifei Zhang, Tianxing Ma +2
The formation of charge-density-wave order in Dirac fermion systems via electron-phonon coupling represents a significant topic in condensed matter physics. In this work, we invest…
Interplay of magnetic and thermodynamic responses in the kagome-triangular system
Zixuan Jia, Lufeng Zhang, Qingzhuo Duan +5
Inspired by the recent experimental progress in pyrochlore derivative RESbAO (A = Mg, Zn), we investigate the Hubbard model on the kagome lattice with an additio…
Dual role of stripe phase on superconducting correlation in a bilayer square lattice
Ting Guo, Lufeng Zhang, Tianxing Ma +1
While the stripe phase has been observed not only in monolayer cuprates but also in bilayer cuprates, research on its behavior in bilayer cuprates has been limited. Using constrain…
Evolution of magnetic correlation in an inhomogeneous square lattice
Xiao Zhang, Runyu Ma, Zenghui Fan +3
We explore the magnetic properties of a two-dimensional Hubbard model on an inhomogeneous square lattice, which provides a platform for tuning the bandwidth of the flat band. In it…
Transport anisotropy and metal-insulator transition in striped Dirac fermion systems
Jingyao Meng, Runyu Ma, Lufeng Zhang +1
Using the determinant quantum Monte Carlo method, we investigate the metal-insulator transitions induced by the stripe of charge density in an interacting two-dimensional Dirac fer…
Magnetic phase transition in disordered interacting Dirac fermion systems via the Zeeman field
Jingyao Meng, Lufeng Zhang, Tianxing Ma +1
Using the determinant quantum Monte Carlo method, we investigate the antiferromagnetic phase transition that is induced by the Zeeman field in a disordered interacting two-dimensio…
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…
Enhancement of -wave pairing in the striped phase with the nearest neighbour attraction
Lufeng Zhang, Ting Guo, Yingping Mou +2
Recently, the experimental results by the angle-resolved photoemission spectroscopy suggested that an additional strong nearest neighbor attraction in the Hubbard model might be si…
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…
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…
