Fermion-fermion interaction driven instability and criticality of quadratic band crossing systems with the breaking of time-reversal symmetry

Ya-Hui Zhai, Jing Wang

We carefully study how the fermion-fermion interactions affect the low-energy states of a two-dimensional spin- $1/2$ fermionic system on the kagomé lattice with a quadratic band cr…

Stability of two-dimensional asymmetric materials with a quadratic band crossing point under four-fermion interaction and impurity scattering

Yao-Ming Dong, Ya-Hui Zhai, Dong-Xing Zheng +1

We investigate the impacts of combination of fermion-fermion interactions and impurity scatterings on the low-energy stabilities of two-dimensional asymmetric materials with a quad…
