Excited states in the dynamic Jahn-Teller effect

Observation of the dynamic Jahn-Teller effect in the excited states of nitrogen-vacancy centers in diamond.

The optical transition linewidth and emission polarization of single nitrogen-vacancy (NV) centers are measured from 5 K to room temperature. Interexcited state population relaxation is shown to broaden the zero-phonon line and both the relaxation and linewidth are found to follow a T(5) dependence for T < 100 K. This dependence indicates that the dynamic Jahn-Teller effect is the dominant deph...

Experimental evidence for the dynamic Jahn-Teller effect in La0.65Ca0.35MnO3.

Recently, it has been argued that a strong electron-phonon interaction arising from the Jahn-Teller splitting of the outer Mn d level plays a crucial role in understanding the nonmetal-to-metal transition observed in the La12xAxMnO3 (A5Ca,Sr,Ba! system. We show, by neutron powder diffraction, that La0.65Ca0.35MnO3 exhibits an anomalous volume and oxygen/manganese displacement change around Tc ,...
