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

Flavio Giorgianni, Martina Romani, Pascal Puphal +5

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