Simple algorithm for evaluating SU(2) non-abelian geometric phase in the vicinity of molecular conical intersection of odd electron number
Chenchen Song
Molecular conical intersection of odd-electron number are known to give arise to non-abelian geometric phases. In this work, we present a simple algorithm for evaluating the SU(2)…

Molecular conical intersections with odd electron number are realizations of the topological Yang monopole
Chenchen Song
The two-level conical intersection of a molecule with odd electron number in the absence of magnetic field obeys time-reversal symmetry (referred to as the co…
