Non-Resonant Magnetic X-ray Scattering as a Probe of Ultrafast Molecular Spin-State Dynamics: An Ab Initio Theory

With the advancement of high harmonic generation and X-ray free-electron lasers (XFELs) to the attosecond domain, the studies of the ultrafast electron and spin dynamics became possible. Yet, the methods for efficient control and measurement of the quantum ...

Topological hysteretic winding for temporal anti-lasing

Romain Christophe Rémy Fleury, Haoye Qin, Zhe Zhang

Coherent perfect absorption (CPA), or anti-lasing, has been so far inherently restricted to continuous wave scenarios, drastically restricting its applications to standard linear steady-state systems. However, future technologies based on enhanced light-ma ...

Nonreciprocal Spin Waves in Nanoscale Hybrid Néel–Bloch–Néel Domain Walls Detected by Scanning X‐Ray Microscopy in Perpendicular Magnetic Anisotropic Fe/Gd Multilayers

Axel Johan Marie Deenen, Dirk Grundler, Andrea Mucchietto, Ping Che, Korbinian Baumgärtl

Spin wave nonreciprocity is crucial for signal processing in magnonic circuits. Domain walls (DWs) have been suggested as channels for nonreciprocal spin waves (magnons) with directional‐dependent properties. However, the experimental investigations are ch ...

Optical imaging of molecules and their dynamics from surfaces to nanoscale confinement

Nathan Cyprien Arsène Ronceray

Molecular behavior can change dramatically at interfaces, and these changes become even more pronounced when molecules are confined within nanoscale dimensions. In living organisms, nanoscale channels play a crucial role in selectively transporting molecul ...

Broadband and high-gain traveling-wave optical parametric amplification in a gallium phosphide photonic integrated circuit

Tobias Kippenberg, Johann Emmeram Riemensberger, Nikolai Kuznetsov, Alisa Davydova, Alberto Nardi

We demonstrate continuous-wave parametric amplifier w ith a 1 40 n m gain bandwidth spanning the optical S,C, and L-bands and up to 25 dB off-chip net-gain in a dispersion engineered gallium phosphide-on-insulator (GaPOI) waveguide with up to 160 mW output ...

Ultrafast hot-carrier dynamics in ultrathin monocrystalline gold

Giulia Tagliabue

Applications in photodetection, photochemistry, and active metamaterials and metasurfaces require fundamental understanding of ultrafast nonthermal and thermal electron processes in metallic nanosystems. Significant progress has been recently achieved in s ...

Engineering nanomaterial surfaces for biomedical applications: antiviral surface coatings, antiviral nanoparticles and lipid-based biopharmaceutical drug systems

Heyun Wang

Nanomaterial surfaces can be engineered by chemical modifications for the modulation of various surface properties including surface charges, hydrophobicity and chemical reactivity. These properties modulate in turn the interactions between the nanomateria ...

Real-time tracking of coherent oscillations of electrons in a nanodevice by photo-assisted tunnelling

Klaus Kern

Coherent collective oscillations of electrons excited in metallic nanostructures (localized surface plasmons) can confine incident light to atomic scales and enable strong light-matter interactions, which depend nonlinearly on the local field. Direct sampl ...
