Exciting atomic oscillations with light is a powerful technique to control the electronic properties of materials, leading to remarkable phenomena such as light-induced superconductivity and ultrafast insulator to metal transitions. Here we show that light-driven lattice vibrations can be utilised to encode efficiently spin information in a magnetic medium. Intense mid-infrared electric field pulses, tuned to resonance with a vibrational normal mode of antiferromagnetic DyFeO3, drive the…

Sum-frequency excitation of coherent magnons

Coherent excitation of magnons is conventionally achieved through Raman scattering processes, in which the difference-frequency components of the driving field are resonant with the magnon energy.

Control of the electronic phase of a manganite by mode-selective vibrational excitation

This work reports the ultrafast switching of the electronic phase of a magnetoresistive manganite via direct excitation of a phonon mode at 71 meV (17 THz), and reports the vibrationally driven bandgap collapse observed here, which is uniquely attributed to a large-amplitude Mn–O distortion.

Light-Induced Superconductivity in a Stripe-Ordered Cuprate

Mid-infrared femtosecond pulses are used to enable coherent transport between the copper oxide planes of a cuprate superconductor, and an upper limit for the time scale needed to form the superconducting phase is estimated to be 1 to 2 picoseconds, which places stringent new constraints on the understanding of stripe order and its relation to superconductivity.
