Topics Tight-binding model, Phase transitions, Topological phases, Topological invariant, Geometric topology The study of topological phases in non-Hermitian systems has taken a center stage in mainstream condensed matter physics ever since it has been realized that stable band-crossing points are more generic and abundant than the Hermitian counterparts.1–4 Stable nodal phases in non-Hermitian Hamiltonians involve the emergence of Exceptional Points (EPs), which are singular points at which...
