Photo-induced nonvolatile rewritable ferroaxial switching

Ultrafast switching of ferroic phases is an active research area with technological potential. Yet, some key challenges remain, ranging from limited speeds in ferromagnets to intrinsic volatility of s...

Cover Story: A recent paper from our theory group has been selected for the cover of the @aip-publishing.bsky.socialAPL Computational Physics Journal 🚀.
They showed that four-component relativistic strong cavity-matter interactions can be approximated by an effective theory with two components.

📢 Publication Alert 📢
Scientists from our theory group have published a new Study in #scienceadvances that shows that you can predict photon-sideband distributions in certain materials using Symmetry-based Floquet Optical Selection.

Scientific Graphic from the Paper.
It shows Disentangling spectral weight distributions in TrARPES via Floquet optical selection rules. The left panel shows a pump-probe setup in a TrARPES experiment on monolayer black phosphorus (BP), where the AC-polarized (s-pol.) pumping laser (blue) is incident perpendicular to the glide-mirror plane and the ZZ-polarized (p-pol.) probe laser (red) lies within this plane. Group-theoretical analysis of the system’s symmetry yields Floquet optical selection rules that govern the visibility of photon-dressed sidebands. The right panel presents a TDDFT-simulated TrARPES intensity plot along the AC direction of BP, obtained from ejected-electron data, with spectral weight distributions across sidebands of different Floquet indices n reflecting the symmetry constraints.
