Fermion-induced quantum critical point in Dirac semimetals: a sign-problem-free quantum Monte Carlo study
Bo-Hai Li, Zi-Xiang Li, Hong Yao
According to Landau criterion, a phase transition should be first order when cubic terms of order parameters are allowed in its effective Ginzburg-Landau free energy. Recently, it…
The thermal Hall conductance of two doped symmetry-breaking topological insulators
Zi-Xiang Li, Dung-Hai Lee
In this paper we study two models of symmetry-breaking topological insulators. They are the variants of the d-density wave Hamiltonian proposed by Chakravarty, Laughlin, Morr and N…
Deconfined quantum criticality and emergent SO(5) symmetry in fermionic systems
Zi-Xiang Li, Shao-Kai Jian, Hong Yao
Deconfined quantum criticality with emergent SO(5) symmetry in correlated systems remains elusive. Here, by performing numerically-exact state-of-the-art quantum Monte Carlo (QMC)…
Disorder induced multifractal superconductivity in monolayer niobium dichalcogenides
Kun Zhao, Haicheng Lin, Xiao Xiao +17
The interplay between disorder and superconductivity is a subtle and fascinating phenomenon in quantum many body physics. The conventional superconductors are insensitive to dilute…
Superconductivity in the presence of strong electron-phonon interactions and frustrated charge order
Zi-Xiang Li, Marvin L. Cohen, Dung-Hai Lee
We study the superconductivity of strongly coupled electron-phonon systems where the geometry of the lattice frustrates the charge order by the sign-problem-free Quantum Monte Carl…
Electronic and phononic properties of a two dimensional electron gas coupled to dipolar phonons via small-momentum-transfer scattering
Zi-Xiang Li, T. P. Devereaux, Dung-Hai Lee
We study the electron and phonon spectral functions as well as superconductivity for a two dimensional electron gas couped to dipolar phonons via small-momentum transfer scattering…
