  • Measuring acoustic phonons across the Brillouin zone reveals important information on electrical and thermal transport in materials. Temnov et al.generate giant acoustic strain pulses in gold/cobalt bilayers and monitor their nonlinear reshaping in the gold layer with plasmonic interferometry.

  • The ability to coherently manipulate single electrons and photons is vital for quantum information processing. Experiments now demonstrate optical initialization, manipulation and probing of a single quantum dot on femtosecond timescales, revealing signatures of interaction effects, optical gain and the ability to change the number of quanta in a light pulse by one.

  • Active switching of plasmons by an external magnetic field is demonstrated in a metal–ferromagnet–metal structure. The strong modulation, combined with possible all-optical magnetization reversal induced by femtosecond light pulses, opens the door to ultrafast magneto-plasmonic switching.
