Anomalous spin dynamics after dual optical excitation
Sergii Parchenko, Peter M. Oppeneer, Andreas Scherz
Ultrashort optical pulses are a cornerstone for manipulating electronic and magnetic states in materials on a femtosecond timescale. Conventional models assume that optical excitat…

Ultrafast decoupling of polarization and strain in ferroelectric BaTiO
Le Phuong Hoang, David Pesquera, Gerard N. Hinsley +20
A fundamental understanding of the interplay between lattice structure, polarization and electrons is pivotal to the optical control of ferroelectrics. The interaction between ligh…
