Understanding cuprate superconductors with spontaneous nodal gap generation
Guo-Zhu Liu, Geng Cheng
We study the spontaneous gap generation for gapless nodal fermions within an effective gauge field theory of high temperature superconductors. When superconductivity appears, the g…

Competing orders in high-T_c superconductors
Guo-Zhu Liu, Geng Cheng
Within a (2+1)-dimensional U(1) gauge field theory, after calculating the Dyson-Schwinger equation for fermion self-energy we find that chiral symmetry breaking (CSB) occurs if the…

The Low-lying Dirac Eigenmodes from Domain Wall Fermions
Guofeng Liu
We calculate the low-lying eigenvalues and eigenvectors of the hermitian domain wall Dirac operator on various gauge backgrounds by Ritz minimization. The mass dependence of these…
