Laser-Induced Skyrmion Writing and Erasing in an Ultrafast Cryo-Lorentz Transmission Electron Microscopy
G. Berruto, I. Madan, Y. Murooka +11
We demonstrate that light-induced heat pulses of different duration and energy can write skyrmions in a broad range of temperatures and magnetic field in FeGe. Using a combination…
Ultrafast generation of hidden phases via energy-tuned electronic photoexcitation in magnetite
B. Truc, P. Usai, F. Pennacchio +8
Metal-insulator transitions (MIT) occurring in non-adiabatic conditions can evolve through high-energy intermediate states that are difficult to observe and control via static meth…
Ultrafast Generation and Control of an Electron Vortex Beam via Chiral Plasmonic Near Fields
G. M. Vanacore, G. Berruto, I. Madan +12
Vortex-carrying matter waves, such as chiral electron beams, are of significant interest in both applied and fundamental science. Continuous wave electron vortex beams are commonly…
meV resolution in laser-assisted energy-filtered transmission electron microscopy
E. Pomarico, I. Madan, G. Berruto +5
The electronic, optical, and magnetic properties of quantum solids are determined by their low-energy (< 100 meV) many-body excitations. Dynamical characterization and manipulation…
Ultrafast holography enabled by quantum interference of ultrashort electrons
I. Madan, G. M. Vanacore, E. Pomarico +7
Holography relies on the interference between a known reference and a signal of interest to reconstruct both the amplitude and phase of that signal. Commonly performed with photons…
From attosecond to zeptosecond coherent control of free-electron wave functions using semi-infinite light fields
G. M. Vanacore, I. Madan, G. Berruto +8
Light-electron interaction in empty space is the seminal ingredient for free-electron lasers and also for controlling electron beams to dynamically investigate materials and molecu…
