  • Directly observing ultrafast single electron dynamics at the atomic scale remains a challenge. Here, the authors demonstrate ultrafast Coulomb blockade at selenium vacancies in WSe2/graphene heterostructures using lightwave-driven scanning tunneling microscopy.

  • Pump-probe spectroscopy is a versatile technique to explore ultrafast dynamics on the femtosecond timescale. Here the authors report a pump-probe experiment and quantum modeling combined study revealing dynamics of collective polaritonic states that are formed between a molecular photoswitch and plasmonic nanoantennas.

  • The microscopic structure of quantum defects in 2D materials is crucial to understand their optical properties and spin-photon interface. Here, the authors report the direct imaging of charge state-dependent symmetry breaking of sulfur vacancies and rhenium dopants in 2D MoS2, showing evidence of a Jahn-Teller effect.

  • All-optical switching allows control of one optical signal using another, holding potential to overcome the limitations of electrical switches via ultrafast manipulation of light. In this work, sub-3 ps all-optical switching is achieved in an epsilon-near-zero nanocavity, exhibiting a relative modulation depth of 120% at a specific wavelength.
