Exceptional Antimodes in Multi‐Drive Cavity Magnonics

Advanced Electronic Materials, EarlyView.
Driven‐dissipative cavity‐magnonics provides a flexible platform for engineering non‐Hermitian physics such as exceptional points. Here, using a four‐port, three‐mode system with controllable microwave interference, antimodes and coherent perfect extinction (CPE) are realized, enabling active tuning to antimode exceptional points.

Centers of projective vector fields of spatial quasi-homogeneous systems with weight $(m,m,n)$ and degree $2$ on the sphere

Electronic Journal of Qualitative Theory of Differential Equations, 2016
In this paper we study the centers of projective vector fields $\mathbf{Q}_T$ of three-dimensional quasi-homogeneous differential system $d\mathbf{x}/dt=\mathbf{Q}(\mathbf{x})$ with the weight $(m,m,n)$ and degree $2$ on the unit sphere $\mathbb{S}^2 ...

Complete polynomial vector fields on the complex plane

Topology, 2004
Let \(v=P(z,w)\partial/\partial z + Q(z,w)\partial/\partial w\) be a complete polynomial vector field on the complex plane \(\mathbb C^ 2\). The author proves that then \(v\) is, up to a polynomial change of coordinates, of one of the three types specified in the main theorem of his paper.

Enhanced High Dimensionality and the Information Processing Capacity in Interfered Spin Wave‐Based Reservoir Computing, Achieved With Eight Detectors

Advanced Electronic Materials, EarlyView.
Physical reservoir computing (PRC) based on spin wave interference has demonstrated high computational performance, yet room for improvement remains. In this study, we fabricated this concept PRC with eight detectors and evaluated the impact of the number of detectors using a chaotic time series prediction task.

Nonlinear differential equations with deviating arguments and approximations via a Parker-Sochacki approach

Electronic Journal of Differential Equations, 2017
The Parker-Sochacki method has been successful in generating approximations for a wide variety of ODEs, and even PDEs of evolution type, by achieving an autonomous polynomial vector field and implementing the Picard iteration.

Galoisian and qualitative approaches to linear Polyanin-Zaitsev vector fields

Open Mathematics, 2018
In this paper we study a particular parametric family of differential equations, the so-called Linear Polyanin-Zaitsev Vector Field, which has been introduced in a general case in [1] as a correction of a family presented in [2].

Uncovering the Role of Intrinsic Magnetic Order in Oxygen Evolution Reaction Activity With Operando Spectroscopy

Advanced Energy Materials, EarlyView.
Operando magnetic spectroscopy provides insight into how intrinsic magnetic order modulates the oxygen evolution reaction on La0.67Sr${\rm La}_{0.67}{\rm Sr}$0.33MnO$_{0.33}{\rm MnO}$3$_3$ thin films. Temperature‐dependent operando FMR and ambient‐pressure XMCD suggest a correlation between activity and the emergence of ferromagnetic regions near and ...

Solving Degree Bounds for Iterated Polynomial Systems

IACR Transactions on Symmetric Cryptology
For Arithmetization-Oriented ciphers and hash functions Gröbner basis attacks are generally considered as the most competitive attack vector. Unfortunately, the complexity of Gröbner basis algorithms is only understood for special cases, and it is ...

Operando X‐Ray Diffraction and Total Scattering Characterization of Battery Materials: Not Just a Pretty Picture

Advanced Energy Materials, EarlyView.
This review focuses on operando studies of battery materials by X‐ray diffraction (XRD) and total X‐ray scattering (TXS). This work highlights potential pitfalls and identify best‐practices for operando studies and reviews some unusual experiments to illustrate how these methods can be applied beyond the evaluation of the early‐stage cycling mechanisms
