Direct observation of enhanced electron-phonon coupling in copper nanoparticles in the warm-dense matter regime
Quynh L. D. Nguyen, Jacopo Simoni, Kevin M. Dorney +12
Warm-dense matter (WDM) is a highly-excited state that lies at the confluence of solids, plasmas, and liquids and that cannot be described by equilibrium theories. The transient na…
Spatially homogeneous few-cycle compression of Yb lasers via all-solid-state free-space soliton management
Bingbing Zhu, Zongyuan Fu, Yudong Chen +11
The high power and variable repetition rate of Yb femtosecond lasers make them very attractive for ultrafast science. However, for capturing sub-200 fs dynamics, efficient, high-fi…
Necklace-structured high harmonic generation for low-divergence, soft X-ray harmonic combs with tunable line spacing
Laura Rego, Nathan J. Brooks, Quynh L. D. Nguyen +6
The extreme nonlinear optical process of high-harmonic generation (HHG) makes it possible to map the properties of a laser beam onto a radiating electron wavefunction, and in turn,…
Non-Equilibrium Dynamics in Two-Color, Few-Photon Dissociative Excitation and Ionization of D
D. S. Slaughter, F. P. Sturm, R. Y. Bello +10
D molecules, excited by linearly cross-polarized femtosecond extreme ultraviolet (XUV) and near-infrared (NIR) light pulses, reveal highly structured D ion fragment momenta…
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…
Thermal transport from 1D- and 2D-confined nanostructures on silicon probed using coherent extreme UV light: General and predictive model yields new understanding
Albert Beardo, Joshua L. Knobloch, Lluc Sendra +9
Heat management is crucial in the design of nanoscale devices as the operating temperature determines their efficiency and lifetime. Past experimental and theoretical works explori…
