  • Despite exhibiting ferroelectric features, SrTiO3 fails to display long-range polar order at low temperatures due to quantum fluctuations. An ultrafast X-ray diffraction experiment now probes polar dynamics of this material at the nanometre scale.

  • Previous studies have suggested that even in the absence of a graphene bandgap, a relaxation bottleneck at the Dirac point may allow for population inversion and lasing. Now, using time- and angle-resolved photoemission spectroscopy with femtosecond extreme-ultraviolet pulses, it is shown that interband excitations give rise to population inversion, suggesting that terahertz lasing may be possible.

  • Quantum Fisher information is a measure of entanglement that has been previously extracted from equilibrium spectra of quantum materials. Here the authors extend this approach to non-equilibrium systems probed by time-resolved resonant inelastic x-ray scattering measurements.

  • Evidence is presented for a Pines’ demon as a three-dimensional acoustic plasmon in the multiband metal Sr2RuO4 from momentum-resolved electron energy-loss spectroscopy using a collimated, defocused beam with high momentum resolution.

  • This work leverages the intrinsic carrier-envelope phase instability of pulsed lasers to measure the photon number distribution of ultrashort probes, providing a new way to study quantum fluctuations in light-driven materials.

  • The manipulation of spins with ultrafast lasers is a promising route to control the properties of a wide variety of quantum materials. Here, the authors present a simulation of Floquet-engineered spin fluctuations in a correlated system and of their fingerprints in ultrafast inelastic X-ray scattering experiments.

  • Interrogating emergent nonequilibrium phenomena in light-driven quantum materials requires probing microscopic spin, charge and orbital excitations at ultrafast timescales. In this Perspective, time-resolved resonant inelastic X-ray scattering is discussed as a nascent method to investigate photoinduced states of matter.
