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…

Lattice dynamics of the infinite-layer nickelate LaNiO $_{2}$

Shohei Hayashida, Vignesh Sundaramurthy, Wenfeng Wu +8

Infinite-layer (IL) nickelates have rapidly emerged as a new class of superconductors. However, due to the technical challenges of their topotactic synthesis, they have so far been…
