Quantum fluctuations of $D_{5d}$ polarons on $C_{60}$ molecules

Abstract

The dynamic Jahn-Teller splitting of the six equivalent $D_{5d}$ polarons due to quantum fluctuations is studied in the framework of the Bogoliubov-de Gennes formalism. The tunneling induced level splittings are determined to be ${}^2{T}_{1u}{⨁}^2{T}_{2u}$ and ${}^1{A}_g{⨁}^1{H}_g$ for $C_{60}^{1-}$ and $C_{60}^{2-}$, respectively, which should give rise to observable effects in experiments.
