The quality of being nonanalytic.
- We identify a topologically driven nonequilibrium phase transition, which is indicated by the nonanalyticity of the Hall conductance as a function of the energy gap m_f in the post-quench Hamiltonian H_f.2015, Pei Wang, Markus Schmitt, Stefan Kehrein, “Universal nonanalytic behavior of the Hall conductance in a Chern insulator at the topologically driven nonequilibrium phase transition”, in arXiv:
