Stimulated magnon scattering by non-degenerate parametric excitation

Joo-Von Kim, Hugo Merbouche

Parametric spin wave excitation allows studying a variety of nonlinear phenomena, such as magnon scattering. In patterned micro- and nanostructures, the magnon spectra is discrete and translational ...

Blue shift of the absorption onset and bandgap bowing in rutile Ge_xSn_1−xO₂

Elias Kluth, Yo Nagashima et al.

The ordinary dielectric functions (DFs) of rutile Ge_xSn_1−xO₂ thin films grown by pulsed laser deposition have been obtained by spectroscopic ellipsometry from the near infrared to the ultraviolet ...

Fast characterization of multiplexed single-electron pumps with machine learning

N. Schoinas, Y. Rath et al.

We present an efficient machine learning based automated framework for the fast tuning of single-electron pump devices into current quantization regimes. It uses a sparse measurement approach based ...

Polarization-dependent photoemission electron microscopy for domain imaging of inorganic and molecular materials

Atreyie Ghosh, Joseph L. Spellberg et al.

Polarization-dependent photoemission electron microscopy (PD-PEEM) exploits spatial variation in the optical selection rules of materials to image domain formation and material organization on the ...

Coupling undetected sensing modes by quantum erasure

Nathan R. Gemmell, Yue Ma et al.

Imaging with undetected photons (IUP) enables the possibility of sensing changes in the phase and the transmission of a beam of light that need never be detected. This has led to the possibility of ...

Lopsided rigid dumbbell rheology from Langevin equation: A graduate tutorial

Nhan Phan-Thien (Phan Thiện Nhân), Dingyi Pan (潘定一) et al.

The modeling of symmetric rigid dumbbell particles suspended in a Newtonian fluid, as a model of a rigid-rod polymeric solution, has been accomplished exclusively through the diffusion equation, ...

Diagnosing up-scattered deuterium–tritium fusion neutrons produced in burning plasmas at the National Ignition Facility (invited)

J. Jeet, B. D. Appelbe et al.

In the push to higher performance fusion plasmas, two critical quantities to diagnose are α-heat deposition that can improve and impurities mixed into the plasma that can limit performance. In ...
