Observation of Relativistic Domain Wall Motion in Amorphous Ferrimagnets

Advanced Functional Materials, Volume 36, Issue 23, 19 March 2026.
Domain walls in ferrimagnets and antiferromagnets move as relativistic sine‐Gordon solitons, with the spin‐wave velocity setting their speed limit. Such relativistic domain‐wall motion is demonstrated in amorphous GdFeCo near angular momentum compensation, where current‐driven walls reach 90% of the 2 kms−1 spin‐wave speed, enabling ultrafast, device ...

Nonclassical Nature of Dispersion Cancellation and Nonlocal Interferometry

, 2009
Several recent papers have shown that some forms of dispersion cancellation have classical analogs and that some aspects of nonlocal two-photon interferometry are consistent with local realistic models.

Probing the Missing Links: Mass Spectrometry of Small‐Molecule Clusters on the Pathway to Fibrils and Crystals

Analysis &Sensing, Volume 6, Issue 2, March 2026.
Mass spectrometry–based technologies reveal how amino acids and metabolites assemble into ordered supramolecular structures. By integrating ion mobility, ion spectroscopy, and condensed‐phase methods, these approaches provide structural insight into small‐molecule assemblies and uncover their emerging biological functions and potential roles in disease.

Bosonic field equations from an exact uncertainty principle

, 2003
A Hamiltonian formalism is used to describe ensembles of fields in terms of two canonically conjugate functionals (one being the field probability density).

Algebraic Active Disturbance Rejection to Control a Generalized Uncertain Second–Order Flat System

International Journal of Applied Mathematics and Computer Sciences
We introduce an algebraically active disturbance rejection-based control solution for the trajectory tracking problem of an uncertain second-order flat system with unknown external disturbances.

Contextual advantage for state discrimination

, 2018
Finding quantitative aspects of quantum phenomena which cannot be explained by any classical model has foundational importance for understanding the boundary between classical and quantum theory.

Based Fault-Tolerance Consensus of Second-Order Heterogeneous System under Input Saturation with Dynamics and Static Leader

Discrete Dynamics in Nature and Society
We focus on fault-tolerant consensus for heterogeneous dynamics systems with static and dynamic leaders under input saturation in this article. We apply theory of finite-time stability to multiagent system cooperative control.

Simple theoretical models for composite rotor blades [PDF]

The development of theoretical rotor blade structural models for designs based upon composite construction is discussed. Care was exercised to include a member of nonclassical effects that previous experience indicated would be potentially important to ...
