If a constant current flows through a superconducting ring, then when the external magnetic field changes, the current in it will change. If a charged body rotates, its angular velocity will change. ...

New measurements of nickelate superconductors reveal clues about their hidden electronic behavior. The mechanism behind high-temperature (TC) superconductivity remains one of condensed matter physics’ major unsolved problems. Chinese researchers have now made important progress in studying high-TC nickelate superconductors. For the first time, scientists identified a nodeless superconducting gap …

This paper proposes an auditable effective scaling law for condensed-matter physics within AQM: macroscopic condensation coherence in a material is not de termined solely by the pairing scale, but by the product of a basic pairing tem perature scale and the AQM coherence protection factor. The factor is ΠAQM = C 2.18(Eeff/E0) 1/2 (1 − δ), where C is topological-orbital coherence, Eeff is effectiv…

The Sovereign CMEC-96(PATENT PENDING): A Continuous Magnetic Energy Converter and Zero-Emission, Utility-Scale Baseload Power Refinery The present invention relates generally to advanced, zero-emission power generation and thermodynamic energy recovery systems. More specifically, it relates to a continuous magnetic energy converter engineered to serve as a direct, decentralized replacement for tr…

A negistor is a npn BJT with the base unconnected, functioning as a replacement for a tunnel diode in certain oscillator circuits, producing negative differential resistance though the voltage current ...

Metals like copper oxidize — reacting with oxygen in the air — but gold doesn’t, thanks to a quick switch in atom arrangement on its surface.

Nature Communications, Published online: 22 May 2026; doi:10.1038/s41467-026-73460-y Nonlinear soliton pumping has recently been observed and understood as the flow of instantaneous Wannier functions. Here, authors find an anomalous nonlinear soliton pump that differs from the linear Chern numbers, arising from soliton transitions between Wannier functions via intersite solitons.

Nature Communications, Published online: 22 May 2026; doi:10.1038/s41467-026-73493-3 When magnetic impurities are present in a metal, conduction electrons form a spin cloud, also termed a Kondo cloud. Here, the authors provide evidence of Kondo clouds and their coupling in devices made up of mirror-symmetric carbon nanotube arrays separated with a molybdenum strip.

Three independently discovered collapse phenomena — in monadic model theory, categorical semantics, and topos theory — share a common fibered descent structure. In each case, target content is constrained to a canonically determined admissible region computed from a source, and collapse occurs when the source is informationally trivial. We identify two modes of canonical admissibility: a reflecti…

Nature Physics, Published online: 21 May 2026; doi:10.1038/s41567-026-03286-4 The potential similarities in the superconductivity in nickelates and cuprates is a topic of debate. Now a distinct likeness is observed in the electronic properties of these materials, which hints that the microscopic mechanisms may be related.
