Plasmon modes in quadratic and cubic nodal line semimetals
Wei Li, Jing-Rong Wang
Nodal line semimetals (NLSMs) host distinctive topological properties and unconventional collective excitations. While plasmons in linear NLSMs are well studied, those of higher-or…
Superconductivity near an Ising nematic quantum critical point in two dimensions
Jie Huang, Zhao-Kun Yang, Jing-Rong Wang +1
Near a two-dimensional Ising-type nematic quantum critical point, the quantum fluctuations of the nematic order parameter are coupled to the electrons, leading to non-Fermi liquid…
Superfluid quantum criticality and the thermal evolution of neutron stars
Hao-Fu Zhu, Guo-Zhu Liu, Jing-Rong Wang +1
The neutron star starts to cool down shortly after its birth by emitting neutrinos. As it becomes cold enough, the Cooper pairs of neutrons are formed, triggering a superfluid tran…
Correlated interaction effects in an anisotropic flat band fermion system
Jing-Rong Wang, Chang-Jin Zhang
An anisotropic flat band fermion system with a novel dispersion that is linear along one direction and cubic along another is proposed in Phys. Rev. X. 13, 021012 (2023). We study…
Comment on "Emergence of Nodal-Knot Transitions by Disorder"
Jing-Rong Wang
In a recent paper arXiv:2409.01034, Gong et al. studied the disorder effects in nodal-knot semimetal through Wilson momentum-shell renormalization group (RG) method. They stated th…
Correlated interaction effects in three-dimensional semi-Dirac semimetal
Jing-Rong Wang, Wei Li, Chang-Jin Zhang
Understanding the correlation effects in unconventional topological materials, in which the fermion excitations take unusual dispersion, is an important topic in recent condensed m…
