Analysis of the Topology of a Plasmonic Target-Skyrmion Texture

Alexander Neuhaus, Pascal Dreher, Philipp Gessler +5

The paper experimentally investigates plasmonic near-field textures that form alternating skyrmion and antiskyrmion patterns, using photoemission electron microscopy and vector pol…

Forecasting with Bayesian Panel Vector Autoregressions Using the R Package bpvars

Miguel Sanchez-Martinez, Tomasz Woźniak

The R package bpvars was designed to forecast employment, unemployment, and labour market participation rates of 189 countries. However, it is generally applicable to dynamic panel…

Linking extended vector wave fields with momentum space topology

A. Neuhaus, P. Gessler, P. Dreher +10

Topology describes properties of physical systems that remain constant under continuous deformations. For infinite vector waves, global topological invariants in position space are…

Electrically detected magnetic resonance of As magnetic clock transitions in silicon

Ravi Acharya, Shao Qi Lim, Brett C. Johnson +9

Magnetic clock transitions (CTs), defined by vanishing first-order sensitivity of the transition frequency to magnetic field fluctuations, provide a powerful route to suppress deco…

Identification Verification for Structural Vector Autoregressions with Sparse Heterogeneous Markov Switching Heteroskedasticity

Fei Shang, Tomasz Woźniak

We propose a structural vector autoregressive model with a new and flexible specification of the volatility process which we call Sparse Heterogeneous Markov-Switching Heteroskedas…

Plasmonic Color Filters Enable Label-Free Plasmon-Enhanced Array Tomography with sub-diffraction limited resolution

Kristian Caracciolo, Eugeniu Balaur, Erinna F. Lee +10

Three-dimensional (3D) imaging of the subcellular organisation and morphology of cells and tissues is essential for understanding biological function. Although staining is the most…
