Determination of the nearest-neighbor interaction in VO via fractal dimension analysis
Jacob Holder, Daniel Kazenwadel, Peter Nielaba +1
The Ising model is one of the simplest and most well-established concepts to simulate phase transformations in complex materials. However, its most central constant, the interactio…
Spatiotemporal attosecond control of electron pulses via subluminal terahertz waveforms
Mikhail Volkov, Eruthuparna Ramachandran, Maximilian Mattes +3
Shaping electron beams with the cycles of light provides femtosecond and attosecond time resolution in electron microscopy and enables fundamental quantum-coherent measurements. Ho…
Free-electron tomography of few-cycle optical waveforms
Yuya Morimoto, Bo-Han Chen, Peter Baum
Ultrashort light pulses are ubiquitous in modern research, but the electromagnetic field of the optical cycles is usually not easy to obtain as a function of time. Field-resolved p…
Polarized phonons carry the missing angular momentum in femtosecond demagnetization
S. R. Tauchert, M. Volkov, D. Ehberger +8
Magnetic phenomena are ubiquitous in our surroundings and indispensable for modern science and technology, but it is notoriously difficult to change the magnetic order of a materia…
Photo-switchable nanoripples in Ti3C2Tx MXene
Mikhail Volkov, Elena Willinger, Denis A. Kuznetsov +3
MXenes are two-dimensional materials with a rich set of remarkable chemical and electromagnetic properties, the latter including saturable absorption and intense surface plasmon re…
Single-cycle optical control of beam electrons
Yuya Morimoto, Peter Baum
Single-cycle optical pulses with a controlled electromagnetic waveform allow to steer the motion of low-energy electrons in atoms, molecules, nanostructures or condensed-matter on…
Asymmetric nonlinear optics of a polar chemical bond
Yuya Morimoto, Yasushi Shinohara, Mizuki Tani +3
A dielectric material's response to light is macroscopically described by electric displacement fields due to polarization and susceptibility, but the atomistic origin is light-cyc…
Attosecond Control of Electron Beams at Dielectric and Absorbing Membranes
Yuya Morimoto, Peter Baum
Ultrashort electron pulses are crucial for time-resolved electron diffraction and microscopy of fundamental light-matter interaction. In this work, we study experimentally and theo…
A tip-based source of femtosecond electron pulses at 30keV
Johannes Hoffrogge, Jan-Paul Stein, Michael Krüger +5
We present a nano-scale photoelectron source, optimized towards ultrashort pulse durations and well-suited for time-resolved diffraction experiments. A tungsten tip, mounted in a s…
