Improved stabilization scheme for extreme ultraviolet quantum interference experiments
Daniel Uhl, Andreas Wituschek, Ulrich Bangert +18
Interferometric pump-probe experiments in the extreme ultraviolet (XUV) domain are experimentally very challenging due to the high phase stability required between the XUV pulses.…
All-optical polarization and amplitude modulation of second-harmonic generation in atomically thin semiconductors
Sebastian Klimmer, Omid Ghaebi, Ziyang Gan +4
Second-harmonic generation is of paramount importance in several fields of science and technology, including frequency conversion, self-referencing of frequency combs, nonlinear sp…
Femtosecond phononic coupling to both spins and charges in a room temperature antiferromagnetic semiconductor
D. Bossini, S. dal Conte, M. Terschanski +7
Spintronics is postulated on the possibility to employ the magnetic degree of freedom of electrons for computation and couple it to charges. In this view, the combination of the hi…
Widefield phototransient imaging for visualizing 3D motion of resonant particles in scattering environments
Matz Liebel, Franco V. A. Camargo, Giulio Cerullo +1
Identifying, visualising and ultimately tracking dynamically moving non-fluorescent nanoparticles in the presence of non-specific scattering is a long-standing challenge across the…
Electrically tuneable nonequilibrium optical response of graphene
Eva A. A. Pogna, Andrea Tomadin, Osman Balci +9
The ability to tune the optical response of a material via electrostatic gating is crucial for optoelectronic applications, such as electro-optic modulators, saturable absorbers, o…
Roadmap on multimode light shaping
Marco Piccardo, Vincent Ginis, Andrew Forbes +35
Our ability to generate new distributions of light has been remarkably enhanced in recent years. At the most fundamental level, these light patterns are obtained by ingeniously com…
Hot-Carrier Cooling in High-Quality Graphene is Intrinsically Limited by Optical Phonons
Eva A. A. Pogna, Xiaoyu Jia, Alessandro Principi +20
Many promising optoelectronic devices, such as broadband photodetectors, nonlinear frequency converters, and building blocks for data communication systems, exploit photoexcited ch…
Angle-tunable intersubband photoabsorption and enhanced photobleaching in twisted bilayer graphene
Eva A. A. Pogna, Xianchong Miao, Driele von Dreifus +7
Van der Waals heterostructures obtained by artificially stacking two-dimensional crystals represent the frontier of material engineering, demonstrating properties superior to those…
