Nodal arc of disordered Dirac fermions and non-Hermitian band theory
© 2019 American Physical Society. We show that Dirac fermion systems in two dimensions generally exhibit a disorder-induced nodal arc replacing the nodal point and tilted Dirac cone, provided that the two components of the Dirac fermion correspond to two distinct orbitals unrelated by symmetry. This...
