Possible instabilities in quadratic and cubic nodal line fermion systems with correlated interactions
Jing-Rong Wang, Wei Li, Chang-Jin Zhang
Influence of short-range four-fermion interactions on quadratic and cubic nodal line fermion systems is studied by renormalization group theory. It is found that arbitrarily weak f…
Towards exact solutions for the superconducting induced by electron-phonon interaction
Guo-Zhu Liu, Zhao-Kun Yang, Xiao-Yin Pan +1
Electron-phonon interaction plays an important role in metals and can lead to superconductivity and other instabilities. Previous theoretical studies on superconductivity are large…
Quantum Criticality of Excitonic Insulating Transition in Nodal Line Semimetal ZrSiS
Jing-Rong Wang, Guo-Zhu Liu, Xiangang Wan +1
Pezzini et al. reported an unconventional mass enhancement in topological nodal line semimetal ZrSiS (Nat. Phys. 14, 178 (2018), whose origin remains puzzling. In this material, st…
Excitonic pairing of two-dimensional Dirac fermions near the antiferromagnetic quantum critical point
Hai-Xiao Xiao, Jing-Rong Wang, Zheng-Wei Wu +1
Two-dimensional Dirac fermions are subjected to two types of interactions, namely the long-range Coulomb interaction and the short-range on-site interaction. The former induces exc…
Effects of the Dirac cone tilt in two-dimensional Dirac semimetal
Zhao-Kun Yang, Jing-Rong Wang, Guo-Zhu Liu
Two-dimensional Dirac semimetal with tilted Dirac cone has recently attracted increasing interest. Tilt of Dirac cone can be realized in a number of materials, including deformed g…
Quantum critical phenomena of the excitonic insulating transition in two dimensions
Xiao-Yin Pan, Jing-Rong Wang, Guo-Zhu Liu
We study the quantum criticality of the phase transition between the Dirac semimetal and the excitonic insulator in two dimensions. Even though the system has a semimetallic ground…
