The Interplay of Crystal‐Field Transitions and Exchange Spin Dynamics in a Ferrimagnet

open access: yesAdvanced Physics Research, EarlyView.
Temperature‐dependent THz spectroscopy reveals strong hybridization between Yb3+ CEF excitations and Yb–Fe exchange dynamics in Gd3/2Yb1/2BiFe5O12. Near the magnetization compensation temperature, spectral weight is redistributed between the coupled modes, while the Yb–Fe exchange mode exhibits an anomalous redshift upon cooling due to CEF‐mediated ...

Application of a Discontinuous Galerkin Method to Predict Airframe Noise [PDF]

open access: yes, 2009
Unstructured grids greatly ease the mesh generation process in the case of complex geometries. The Discontinuous Galerkin Method (DGM) provides a robust, high-order accurate discretization even on this type of grid.

Calculation of the neutron noise using the Analytical Nodal Method

open access: yes, 2009
In this study, the neutron noise, i.e. the stationary fluctuations of the neutron flux around its mean value, is calculated in 2-group diffusion theory for a 2-dimensional reactor using the Analytical Nodal Method.

Interferometric Scattering Microscopy (iSCAT): A Perspective on Visualizing and Engineering Electrode Homogeneity for Advanced Lithium‐Ion Batteries

open access: yesCarbon Energy, EarlyView.
Electrode state‐of‐charge heterogeneity critically limits lithium‐ion battery performance and safety. This Perspective highlights iSCAT, a powerful optical technique for real‐time, nanoscale visualization of lithium dynamics within single particles. By revealing the origins of heterogeneity, iSCAT enables rational electrode design.
