Coulomb analogy for non-Hermitian degeneracies near quantum phase transitions.

Daniel López García · Physical Review Letters · 2007

Summary

A method is presented to measure distributions of degeneracies on the Riemann sheet of a selected level and apply it in classification of quantum phase transitions of a Hermitian Hamiltonian.
