The nature of effective interaction in cuprate superconductors: a sign-problem-free quantum Monte-Carlo study
Zi-Xiang Li, Fa Wang, Hong Yao +1
Superconductivity is an emergent phenomena in the sense that the energy scale associated with Cooper pairing is generically much lower than the typical kinetic energy of electrons.…
What makes the Tc of monolayer FeSe on SrTiO3 so high: a sign-problem-free quantum Monte Carlo study
Zi-Xiang Li, Fa Wang, Hong Yao +1
Monolayer FeSe films grown on SrTiO3 (STO) substrate show superconducting gap-opening temperatures (Tc) which are almost an order of magnitude higher than those of the bulk FeSe an…
Topological versus Landau-like phase transitions
Lokman Tsui, Fa Wang, Dung-Hai Lee
The study of continuous phase transitions triggered by spontaneous symmetry breaking has brought new concepts that revolutionized the way we understand many-body systems. Recently,…
Magnetic interactions in FeSe studied by first principle calculations
Shuai Wang, Fa Wang
Based on first principle calculations we have investigated the evolution of magnetism in free-standing monolayer FeSe with respect to lattice constant and magnetism in bulk FeSe. T…
Quantum oscillation in narrow-gap topological insulators
Long Zhang, Xue-Yang Song, Fa Wang
The canonical understanding of quantum oscillation in metals is challenged by the observation of de Haas-van Alphen effect in an insulator, SmB [Tan \emph{et al}, Science {\b…
Schwinger boson spin liquid states on square lattice
Xu Yang, Fa Wang
We study possible spin liquids on square lattice that respect all lattice symmetries and time-reversal symmetry within the framework of Schwinger boson (mean-field) theory. Such sp…
