Ultrafast RIXS of orbital-resolved valence-band reshaping in photoexcited graphite

Ultrafast photoexcitation can drive solids far from equilibrium by dynamically renormalizing their electronic structure, yet direct time-domain access to bulk band-structure reshaping with orbital and momentum selectivity has remained limited. Here, we show in photoexcited graphite that femtosecond carbon K-edge resona...

Raman signatures of a non-reciprocal magnetic phase transition in Ca$_2$RuO$_4$

The magnetic behavior of Ca$_2$RuO$_4$ represents a unique puzzle due to the interplay of strong electronic correlations, magneto-elastic interactions, and large spin-orbit coupling. At low temperatures, an anomalous Mott insulating state emerges, characterized by a complex antiferromagnetic order with a collective amp...
