  Resonant enhancement of photo-induced superconductivity in K₃C₆₀

  There is evidence that K₃C₆₀ can host a photo-induced superconducting state. Now, resonant excitation at low frequencies allows this phenomenon at room temperature and low pumping fluence.

  Ultrafast switching to an insulating-like metastable state by amplitudon excitation of a charge density wave

  Ultrafast optical excitation of a charge density wave leads to the formation of a metastable gapped state that synchronizes with the underlying correlated phase.

  Evidence for metastable photo-induced superconductivity in K₃C₆₀

  Evidence for light-induced superconductivity in K₃C₆₀ was limited to optical methods due to the short lifetime of the phase. Extending the lifetime from picoseconds to nanoseconds now allows measurement of its negligible electrical resistance.

  Terahertz control of nanotip photoemission

  Nanoscale metallic tips are a useful source of electrons for material characterization. It is now shown how terahertz radiation can provide precision control and enhancement of photoelectron emission from these sources. The approach can shape the spectrum of the electron pulse, which could pave the way to improvements in ultrafast electron diffraction and transmission electron microscopy.
