Ultrafast light-induced shear strain probed by time-resolved X-ray diffraction: the model multiferroic BiFeO as a case study
V. Juvé, R. Gu, S. Gable +12
Enabling the light-control of complex systems on ultra-short timescales gives rise to rich physics with promising applications. While crucial, the quantitative determination of bot…

On the magnetoelastic and magnetoelectric couplings across the antiferromagnetic transition in multiferroic BiFeO3
Mariusz Lejman, Charles Paillard, Vincent Juvé +7
Clear anomalies in the lattice thermal expansion (deviation from linear variation) and elastic properties (softening of the sound velocity) at the antiferromagnetic-to-paramagnetic…

Exciton Control in a Room-Temperature Bulk Semiconductor with Coherent Strain Pulses
Edoardo Baldini, Adriel Dominguez, Tania Palmieri +4
The coherent manipulation of excitons in bulk semiconductors via the lattice degrees of freedom is key to the development of acousto-optic and acousto-excitonic devices. Wide-bandg…
