Spontaneous Raman scattering as a probe of vibrational quantum coherence and plasmonic near-field

Spontaneous vibrational Raman scattering is a ubiquitous form of light-matter interaction whose description necessitates quantization of the electromagnetic field. It is usually considered an incoherent process since it stems from the fluctuations of the v ...

From STEM-EDXS data to phase separation and quantification using physics-guided NMF

Thomas Tim Holvoet, Cécile Hébert, Duncan Thomas Lindsay Alexander, Nathanaël Perraudin, Guillaume Romain Obozinski

We present the development of a new algorithm which combines state-of-the-art energy-dispersive x-ray (EDX) spectroscopy theory and a suitable machine learning formulation for the hyperspectral unmixing of scanning transmission electron microscope EDX spec ...

Moving objects in diverse media through wave momentum manipulation

Romain Christophe Rémy Fleury, Bakhtiyar Orazbayev, Matthieu Francis Malléjac

In this paper, we experimentally demonstrate the ability to move an object in disordered and dynamic media by using acoustic waves for transferring linear or angular momentum to the object. In contrast to the remarkable results that have been achieved in o ...

Free Electron Interaction with Nonlinear Optical States

Tobias Kippenberg, Rui Ning Wang, Arslan Sajid Raja, Guanhao Huang, Zheru Qiu, Alexey Tikan, Aleksandr Tusnin, Yujia Yang

We couple free electrons with nonlinear optical states and frequency combs in photonic chip-based microresonators. Intracavity nonlinear dissipative structures including optical solitons imprint unique fingerprints in electron spectra and their Ramsey inte ...

Accurate Prediction of Hall Mobilities in Two-Dimensional Materials through Gauge-Covariant Quadrupolar Contributions

Nicola Marzari

Despite considerable efforts, accurate computations of electron-phonon and carrier transport properties of low-dimensional materials from first principles have remained elusive. By building on recent advances in the description of long-range electrostatics ...

Roadmap on wavefront shaping and deep imaging in complex media

Demetri Psaltis, Christophe Moser, Babak Rahmani

The last decade has seen the development of a wide set of tools, such as wavefront shaping, computational or fundamental methods, that allow us to understand and control light propagation in a complex medium, such as biological tissues or multimode fibers. ...

Selective Integrin alpha(5)beta(1) Targeting through Spatially Constrained Multivalent DNA-Based Nanoparticles

Maartje Martina Cornelia Bastings, Vincenzo Caroprese, Diana Kornelia Morzy, Eva Eugene Kurisinkal, Marianna Mainardi Koga

Targeting cells specifically based on receptor expression levels remains an area of active research to date. Selective binding of receptors cannot be achieved by increasing the individual binding strength, as this does not account for differing distributio ...

A method for cleaning flat punch diamond microprobe tips

Andreas Mortensen, Alejandra Inés Slagter, Joris Pierre Everaerts

Microprobe tips are commonly used to perform in-situ micromechanical tests within an electron microscope. In service, such tips have a tendency to accumulate along their surface a layer of deposited material. Tip cleanliness is crucial in order to obtain r ...

Eigenmode Analysis in Plasmonics: Application to Second Harmonic Generation and Electron Energy Loss Spectroscopy

Gabriel David Bernasconi

Eigenmodes are central to the study of resonant phenomena in all areas of physics. However, their use in nano-optics seems to have been hindered and delayed for various reasons. First, due to their small size, the response of nanostructures to a far-field ...

Structure analysis of the YBCO layer in Ag/YBCO/metal oxide buffer/Hastelloy composite tape before and after 107 MeV Kr17+ irradiation

Philippe Buffat, Elena Suvorova Buffat, Marco Cantoni

The effects of 107 MeV Kr-84(17+) ion irradiation on YBa2Cu3O7-x-based second-generation coated conductors were investigated using a combination of transmission electron microscopy, diffraction and X-ray energy dispersive spectrometry. Defects 3-5 nm in di ...
