The Bernina group works on experimental studies of beyond-equilirium ultrafast phenomena in condensed matter. It develops and operates the Bernina Instrument of SwissFEL, which is presently under commissioning and performing first experiments. The group arises from the FEMTO group at the Swiss Light Source.

Short x-ray pulses reveal the source of light-induced ferroelectricity

Ultrafast measurements of the fluctuating atomic positions in the quantum paraelectric SrTiO3 after mid-infrared light excitation, reveal details about the creation of the material’s ferroelectric state.
