  • Direct observation of light-induced topological Floquet states can be challenging due to a number of obstacles such as laser-assisted photoemission which can complicate photoemission spectra. Here, the authors report a theoretical approach to the identification of topological Floquet states using circular dichroism in angle resolved photoemission spectroscopy.

  • Here, the authors show the emergence of valley-polarized Floquet-Bloch states in 2H-WSe2 upon below-band-gap driving using circularly polarized light.

  • Strong light-matter interaction provides opportunities for engineering electronic symmetry on an ultrafast timescale by forming photon-dressed states called Floquet-Bloch states. Here, the authors observe parity manipulation of Floquet-Bloch states by light fields in a model semiconductor - black phosphorus.

  • The build-up and dephasing of Floquet-–Bloch bands is visualized in both subcycle band-structure videography and quantum theory, revealing the interplay of strong-field intraband and interband excitations in a non-equilibrium Floquet picture.

  • Angle-resolved photoemission spectroscopy (ARPES) is widely used to study the electronic structure of a wide range of correlated materials. Time-resolved ARPES allows the study of the response of such electronic features on ultrafast timescales; this paper now adds an exciting new dimension by using high photon energies that allow the study of ultrafast dynamics at high momenta, where often the most interesting fundamental phenomena occur. The technique is applied to the charge density wave material 1T-TiSe2 and it is shown with stroboscopic imaging of the electronic band structure at high momentum that atomic-scale periodic long-range order collapses on a surprisingly short timescale of 20 femtoseconds.

  • The non-equilibrium dynamics of correlated electron materials are still poorly understood. Here, the authors use time- and angle-resolved photoemission spectroscopy to show that carrier multiplication is important in initial non-equilibrium dynamics of 1T-TiSe2and depends on the size of the energy gap.

  • Lape et al. use electronic health records and a discovery-replication cohort study design to investigate links between common pathogens and non-communicable diseases. Evidence is found for over 200 associations, such as a role for human cytomegalovirus in ulcerative colitis.

  • Strontium isotope analysis can be applied to animal and plant tissues to help determine their provenance. Here, the authors generate a strontium isoscape of sub-Saharan Africa using data from 2266 environmental samples and demonstrate its efficacy by tracing the African roots of individuals from historic slavery contexts.
