Probing the real-space density of spin-entangled electrons
Federico Pisani, Leonie Spitz, Libor VojáÄek +12
On the textbook example of an isolated antiferromagnetic Heisenberg dimer, we demonstrate that the magnetic form factor and the magnetic electron density distribution can be extrac…
All-optical control of second-harmonic generation in -BaBO via coherent, terahertz-driven acentric lattice displacement
Flavio Giorgianni, Nicola Colonna, Gabriel Nagamine +6
Dynamical control of the nonlinear optical properties of solids -- with light itself -- will be essential for future ultrafast photonic technologies. Previously, methods to modulat…
Terahertz light driven coherent excitation of a zone-folded Raman-active phonon mode in the Spin-Ladder System -NaVO
Flavio Giorgianni, Martina Romani, Pascal Puphal +5
We investigate the out-of-equilibrium lattice dynamics in the spin-ladder system -NaVO 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…
