Non-linear enhancement of ultrafast X-ray diffraction through transient resonances

Diffraction-before-destruction imaging with ultrashort X-ray pulses can visualize non-equilibrium processes, such as chemical reactions, with sub-femtosecond precision in the native environment. Here, a nanospecimen diffracts a single X-ray flash before it ...

First 2D electron density measurements using multi-delay coherence imaging spectroscopy in the MAST-U Super-X divertor

Christian Gabriel Theiler

2D profiles of electron density and neutral temperature are inferred from multi-delay coherence imaging spectroscopy data of divertor plasmas using a non-linear inversion technique. The inference is based on imaging the spectral line-broadening of Balmer l ...

Nanoplasmonic Infrared Microarray Sensor Enabling Structural Protein Biomarker-Based Drug Screening for Neurodegenerative Diseases

Berkay Dagli, Hilal Lashuel, Hatice Altug, Deepthy Kavungal, Enzo Sébastien Benjamin Morro

The misfolding of proteins from native monomers into β-sheet-rich fibrils via oligomers is a key hallmark of neurodegenerative diseases (NDDs). Identifying and screening drugs that inhibit protein aggregation for early disease intervention remains challeng ...

Testing the accuracy and convergence of scattering calculations using Lorentz reciprocity

Olivier Martin, Andrei Kiselev

We present a simple and versatile approach to test the accuracy of scattering calculations. Based on the Lorentz reciprocity relation, this criterion can be used for any scattering object, especially where a reference solution (e.g. from Mie theory) does n ...

Field-Resolved Detection of Broadband Terahertz Pulses with Thin-Film Lithium Niobate Integrated Microring Resonators

Ileana-Cristina Benea-Chelmus, Alessandro Tomasino, Jiawen Liu

The Terahertz (THz) frequency domain lies between the realms of microwave and optics, with frequencies conventionally spanning the 0.1-10 THz spectral range [1]. Many commercially-available THz systems routinely exploits optical down/up conversion mechanis ...

Plasmonic biosensor enabled by resonant quantum tunnelling

Hatice Altug, Ivan Sinev, Mikhail Masharin

Metasurfaces provide an ideal platform for optical sensing because they produce strong light-field confinement and enhancement over extended regions that allow us to identify deep-subwavelength layers of organic and inorganic molecules. However, the requir ...

Motional Sideband Asymmetry of a Solid-State Mechanical Resonator at Room Temperature

Tobias Kippenberg, Guanhao Huang, Nils Johan Engelsen, Alberto Beccari, Amirali Arabmoheghi, Alessio Zicoschi

The motional sideband asymmetry of a mechanical oscillator interacting with a laser field can be observed when approaching the quantum ground state, where the zero-point energy of the mechanical oscillator becomes a sizable contribution to its motion. In t ...
