  • The authors report the emergence of a transient hexatic state during laser-induced transformation between two charge-density wave (CDW) phases in a thin film of the CDW material 1T-TaS2.

  • Coulomb interactions in free-electron beams are usually seen as an adverse effect. The creation of distinctive number states with one, two, three and four electrons now reveals unexpected opportunities for electron microscopy and lithography from Coulomb correlations.

  • Electron holography and microscopy have long been used to map static electric and magnetic fields. Here, authors establish Lorentz Microscopy of Optical Fields, a new technique that uses the deflection and interference of an electron beam to obtain phase-resolved images of nanoscale optical fields.

  • The coherent manipulation of electron quantum states using light, commonly employed in atoms and molecules, is extended to the case of free electron beams using ultrafast transmission electron microscopy; this approach may enable a range of applications in ultrafast electron imaging and spectroscopy down to attosecond precision.
