  • Time- and angle-resolved photoemission spectroscopy now resolves the long-sought avoided crossing in light-driven graphene, establishing a practical recipe for Floquet band engineering and sharpening prospects for light-induced topology in quantum materials.

  • The feasibility of Floquet engineering in graphene has been called into question due to its fast decoherence processes. Measurements of graphene’s photoemission spectrum now support the generation of Floquet states in this material.

  • Multidimensional time- and angle-resolved photoelectron spectroscopy is used to determine the interlayer exciton formation process, reveal a direct hallmark of the superlattice moiré modification, and reconstruct the real-space wavefunction distribution.

  • Optical intersite spin transfer (OISTR), which is driven by an ultrafast optical excitation, was recently found in several materials, but there is some disagreement over how this phenomenon can be observed experimentally. Here, the authors investigate the mechanism of intersite spin transfer in a set of FeNi alloys and make a comparison with pure Ni, demonstrating and discussing the challenges of observing OISTR using magneto-optical measurements.

  • Understanding excitonic optical excitations is integral to improving optoelectronic and photovoltaic semiconductor devices. Here, Bennecke et al. use photoemission exciton tomography to unravel the multiorbital electron and hole contributions of entangled excitonic states in the prototypical organic semiconductor C60.
