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 ...

Conformal theory of gravitation and cosmology
, 2020 The postulate of universal local Weyl scaling (conformal) symmetry modifies both general relativity and the Higgs scalar field model. Conformal gravity (CG) has recently been fitted to rotation data for 138 galaxies.

On the Concept of a Notational Variant [PDF]
, 2017 In the study of modal and nonclassical logics, translations have frequently been employed as a way of measuring the inferential capabilities of a logic.

Why the Disjunction in Quantum Logic is Not Classical [PDF]
, 2000 The quantum logical `or' is analyzed from a physical perspective. We show that it is the existence of EPR-like correlation states for the quantum mechanical entity under consideration that make it nonequivalent to the classical situation.

On the origin of nonclassicality in single systems
, 2017 In the framework of certain general probability theories of single systems, we identify various nonclassical features such as incompatibility, multiple pure-state decomposability, measurement disturbance, no-cloning and the impossibility of certain ...

Hyperentanglement in Nanophotonic Systems With Discrete Rotational Symmetry
Nanophotonics, Volume 15, Issue 6, 27 March 2026.This work introduces a nanophotonic scheme leveraging discrete rotational symmetry to unlock two quantum capabilities: generation of hyperentangled photon pairs in spin and spatial degrees of freedom; and isomorphic mapping that preserves free‐space degrees of freedom, overcoming the information loss in non‐paraxial photonic systems.

Electron-radiation interaction in a Penning trap: beyond the dipole approximation
, 1998 We investigate the physics of a single trapped electron interacting with a radiation field without the dipole approximation. This gives new physical insights in the so-called geonium theory.Comment: 12 pages, RevTeX, 6 figures, Approved for publication ...

Noûs, Volume 60, Issue 1, Page 136-160, March 2026.Abstract It is well‐recognized in the sciences that a multitude of nonequivalent models are used by researchers to fulfill a range of goals, even for the same target system, a result known broadly as model pluralism. The possibility of the same form of pluralism occurring in logic, however, has not been adequately considered.

Selective interactions in trapped ions: state reconstruction and quantum logic
, 2003 We propose the implementation of selective interactions of atom-motion subspaces in trapped ions. These interactions yield resonant exchange of population inside a selected subspace, leaving the others in a highly dispersive regime. Selectivity allows us

MedComm, Volume 7, Issue 2, February 2026.Neurons, immune cells, and other cellular components within the disease microenvironment (such as stromal cells and tumor cells) constitute a dynamically evolving ecosystem. Neurons directly modulate immune cell activity and inflammatory responses through the release of neurotransmitters (e.g., norepinephrine and CGRP), while also promoting tumor ...
