Geometric phase effects in dynamics near conical intersections: Symmetry
breaking and spatial localization
   [PDF]

Ilya G. Ryabinkin, Artur F. Izmaylov
We show that finite systems with conical intersections can exhibit spontaneous symmetry breaking which manifests itself in spatial localization of eigenstates. This localization has a geometric phase origin and is robust against variation of model parameters. The transition between localized and delocalized eigenstate regimes resembles a continuous phase transition. The localization slows down the low-energy quantum nuclear dynamics at zero and low temperatures.
