Terahertz light driven coherent excitation of a zone-folded Raman-active phonon mode in the Spin-Ladder System $I^\pm^{'}$ -NaV $_{2}$ O $_{5}$

Flavio Giorgianni, Martina Romani, Pascal Puphal +5

We investigate the out-of-equilibrium lattice dynamics in the spin-ladder system $I^\pm^{'}$ -NaV $_{2}$ O $_{5}$ using intense terahertz (THz) pump and near-infrared (NIR) probe spectroscopy. W…

Direct Evidence of Metal-Ligand Redox in Li-ion Battery Positive Electrodes

Galo J. Paez Fajardo, Daniela Dogaru, Hrishit Banerjee +15

Describing Li-ion battery positive electrodes in terms of distinct transition metal or oxygen redox regimes can lead to confusion in understanding metal-ligand hybridisation, oxyge…
