Tuning chirality amplitude at ultrafast timescales in chiral CsCuCl3
We quantify “how chiral” a crystal is, and demonstrate its tunability at ultrafast timescales. This achievement does open up a new direction in chirality-related condensed matter physics and on emergent phenomena, which have both attracted significant attention recently.
Stabilising fleeting quantum states with light
X-rays from SwissFEL probe emergent properties of quantum materials
Elusive multiferroicity in RNiO3 perovskites
In our recent paper we examined YNiO3 and proved that the RNiO3 type material known for its metal-insulator transition is in fact a type II multiferroic. We provide direct evidence of an electric-field-driven switch of the noncolliear magnetic state finally confirming the proposed type II multiferroic nature of YNiO3.
