Nanoscale Nonlinear Spectroscopy with Electron Beams
Andrea Konečná, Valerio Di Giulio, Vahagn Mkhitaryan +2
We theoretically demonstrate the ability of electron beams to probe the nonlinear photonic response with nanometer spatial resolution, well beyond the capabilities of existing opti…
Controlling free electrons with optical whispering-gallery modes
Ofer Kfir, Hugo Lourenço-Martins, Gero Storeck +5
Free-electron beams serve as uniquely versatile probes of microscopic structure and composition, and have repeatedly revolutionized atomic-scale imaging, from solid-state physics t…
Structural Dynamics of incommensurate Charge-Density Waves tracked by Ultrafast Low-Energy Electron Diffraction
Gero Storeck, Jan Gerrit Horstmann, Theo Diekmann +5
We study the non-equilibrium structural dynamics of the incommensurate and nearly-commensurate charge-density wave phases in 1T-TaS. Employing ultrafast low-energy electron dif…
Nonlinear Spectroscopy and All-Optical Switching of Femtosecond Soliton Molecules
Felix Kurtz, Claus Ropers, Georg Herink
The emergence of confined structures and pattern formation are exceptional manifestations of concurring nonlinear interactions found in a variety of physical, chemical and biologic…
Few-nm tracking of magnetic vortex orbits and their decay with ultrafast Lorentz microscopy
Marcel Möller, John Henri Gaida, Sascha Schäfer +1
Transmission electron microscopy is one of the most powerful techniques to characterize nanoscale magnetic structures. In light of the importance of fast control schemes of magneti…
Density Matrix Reconstructions in Ultrafast Transmission Electron Microscopy: Uniqueness, Stability, and Convergence Rates
Cong Shi, Claus Ropers, Thorsten Hohage
In the recent paper [17] the first experimental determination of the density matrix of a free electron beam has been reported. The employed method leads to a linear inverse problem…
