Slater and Mott insulating states in the SU(6) Hubbard model
Da Wang, Lei Wang, Congjun Wu
We perform large scale projector determinant quantum Monte-Carlo simulations to study the insulating states of the half-filled SU(6) Hubbard model on the square lattice. The transi…
Superconductivity, pair density wave, and Neel order in cuprates
Li-Han Chen, Da Wang, Yi Zhou +1
We investigate in underdoped cuprates possible coexistence of the superconducting (SC) order at zero momentum and pair density wave (PDW) at momentum in the presen…
Chiral and helical -wave superconductivity in doped bilayer BiH
L. Yang, W. S. Wang, D. Wang +1
We investigate the superconductivity (SC) driven by correlation effects in electron-doped bilayer BiH near a type-II van Hove singularity (vHS). By functional renormalization group…
Critical exponents of nonlinear sigma model on Grassmann manifold by expansion
Shan-Yue Wang, Da Wang, Qiang-Hua Wang
Motivated by the numerical evidence of a continuous phase transition between antiferromagnetic and paramagnetic phases in the half-filled SU(N) Hubbbard model, we studied its low e…
Entanglement in a second order topological insulator on a square lattice
Qiang Wang, Da Wang, Qiang-Hua Wang
In a -dimensional topological insulator of order , there are zero energy states on its corners which have close relationship with its entanglement behaviors. We studied the b…
Via Method for Lithography Free Contact and Preservation of 2D Materials
Evan J. Telford, Avishai Benyamini, Daniel Rhodes +10
Atomically thin 2D materials span the common components of electronic circuits as metals, semi-conductors, and insulators, and can manifest correlated phases such as superconductiv…
