Fieldoscopy at the Quantum Limit
Dmitry A. Zimin, Arjun Ashoka, Florentin Reiter +1
We demonstrate a novel concept for measuring time-varying electric field transients of petahertz-scale photons down to a single-photon regime. We observe a clear transition from cl…

Room Temperature Optically and Magnetically Active Edges in Phosphorene Nanoribbons
Arjun Ashoka, Adam J. Clancy, Naitik A. Panjwani +20
Nanoribbons - nanometer wide strips of a two-dimensional material - are a unique system in condensed matter physics. They combine the exotic electronic structures of low-dimensiona…
