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…

Entropy-assisted, long-period stacking of honeycomb layers in an AlB2-type silicide

Leonie Spitz, Takuya Nomoto, Shunsuke Kitou +8

Configurational entropy can impact crystallization processes, tipping the scales between structures of nearly equal internal energy. Using alloyed single crystals of Gd2PdSi3 in th…
