Second-harmonic generation and the conservation of spatiotemporal orbital angular momentum of light
Guan Gui, Nathan J. Brooks, Henry C. Kapteyn +2
Light with spatiotemporal orbital angular momentum (ST-OAM) is a recently discovered type of structured and localized electromagnetic field. This field carries characteristic space…
Direct observation of 3D topological spin textures and their interactions using soft x-ray vector ptychography
Arjun Rana, Chen-Ting Liao, Ezio Iacocca +21
Magnetic topological defects are energetically stable spin configurations characterized by symmetry breaking. Vortices and skyrmions are two well-known examples of 2D spin textures…
Light with a self-torque: extreme-ultraviolet beams with time-varying orbital angular momentum
Laura Rego, Kevin M. Dorney, Nathan J. Brooks +11
Twisted light fields carrying orbital angular momentum (OAM) provide powerful capabilities for applications in optical communications, microscopy, quantum optics and microparticle…
Beyond the single-atom response in absorption lineshapes: Probing a dense, laser-dressed helium gas with attosecond pulse trains
Chen-Ting Liao, Arvinder Sandhu, Seth Camp +2
We investigate the absorption line shapes of laser-dressed atoms beyond the single-atom response, by using extreme ultraviolet (XUV) attosecond pulse trains to probe an optically t…
