Laser-induced real-space topology control of spin wave resonances
Tim Titze, Sabri Koraltan, Timo Schmidt +8
Femtosecond laser excitation of materials that exhibit magnetic spin textures promises advanced magnetic control via the generation of ultrafast and non-equilibrium spin dynamics.…
Coherent x-ray magnetic imaging with 5 nm resolution
Riccardo Battistelli, Daniel Metternich, Michael Schneider +13
Soft x-ray microscopy plays an important role in modern spintronics. However, the achievable resolution of most x-ray magnetic imaging experiments is above 10 nm, limiting access t…
Free-electron interaction with nonlinear optical states in microresonators
Yujia Yang, Jan-Wilke Henke, Arslan S. Raja +10
The short de Broglie wavelength and strong interaction empower free electrons to probe scattering and excitations in materials and resolve the structure of biomolecules. Recent adv…
Attosecond electron microscopy by free-electron homodyne detection
John H. Gaida, Hugo Lourenço-Martins, Murat Sivis +4
Time-resolved electron microscopy aims at tracking nanoscale excitations and dynamic states of matter with a temporal resolution ultimately reaching the attosecond regime. Periodic…
High-sensitivity extreme-ultraviolet transient absorption spectroscopy enabled by machine learning
Tobias Heinrich, Hung-Tzu Chang, Sergey Zayko +2
We introduce a machine-learning-based approach to enhance the sensitivity of optical-extreme ultraviolet (XUV) transient absorption spectroscopy. A reference spectrum is used as in…
Spatiotemporal Electron-Beam Focusing through Parallel Interactions with Shaped Optical Fields
F. Javier García de Abajo, Claus Ropers
The ability to modulate free electrons with light has emerged as a powerful tool to produce attosecond electron wavepackets. However, research has so far aimed at the manipulation…
