Exceptional Points and Dynamical Phase Transitions
... Schrödinger equation is nonlinear and the levels are mixed (entangled) in the parameter range in which the resonances overlap. The parameter range shrinks to one point when the levels cross, i.e. when rk → 0 and (8) is approached. Secondly, a dynamical phase transition is induced by exceptional poi ...
