A tunable feedback-controlled magnetic trap for a magnet in free fall
arXiv:2606.01056v1 Announce Type: new Abstract: Ferromagnets in free space are predicted to exhibit pure Larmor precession at near-zero magnetic fields and provide exceptional sensitivity for magnetometry and gyroscopy. Notably, pure Larmor precession has not been observed in a macroscopic ferromagnetic particle, despite its fundamental importance and potential for probing relativistic effects and dark-matter interactions.
High-Load-Density Electro-Permanent Magnetic Foot with Controllable Adhesion for Quadruped Wall-Climbing Robots
Announce Type: new Abstract: To enable reliable climbing locomotion of quadruped robots on ferromagnetic surfaces, this paper presents a high-load-density electro-permanent magnetic foot with controllable adhesion, featuring force-feedback circular Halbach-net electro-permanent magnet (CHN-EPM) adhesion units and a magnetization control system. Due to its three-dimensional magnetic circuit structure and flux-concentration effect, the CHN-EPM enables a distributed parallel magnetic flux path...
Experimental Demonstration of a Decentralized Electromagnetic Formation Flying Control Using Alternating Magnetic Field Forces
arXiv:2601.05408v4 Announce Type: replace Abstract: Electromagnetic formation flying (EMFF) is challenging due to the complex coupling between the electromagnetic fields generated by each satellite in the formation. To address this challenge, this article uses alternating magnetic field forces (AMFF) to decouple the electromagnetic forces between each pair of satellites. The key idea of AMFF is that a pair of alternating (e.g., sinusoidal) magnetic moments results in a nonzero time-averaged...
Scientists discover a hidden quantum world inside cobalt
Scientists discover a hidden quantum world inside cobalt - Date: - June 5, 2026 - Source: - Helmholtz-Zentrum Berlin - Summary: - Scientists have uncovered unexpected quantum complexity inside cobalt, a metal long thought to be fully understood. Advanced measurements revealed a dense network of topological electronic states that remain robust at room temperature. These states enable extremely fast electron behavior and can be switched or controlled using magnetism.
Near-axis quasi-isodynamic database
arXiv:2601.08400v3 Announce Type: replace Abstract: In this work, we investigate the landscape of quasi-isodynamic stellarators using the near-axis expansion of the magnetic field. Building on recent theoretical developments, we construct a database of more than 800,000 stable, approximately quasi-isodynamic vacuum magnetic configurations. These configurations span a range of field period numbers and other geometric control parameters, including the magnetic axis shape and plasma elongation.
Chiral superfluorescence from perovskite superlattices at room temperature
Nature, Published online: 03 June 2026; doi:10.1038/s41586-026-10637-xChiral perovskite superlattices exhibit room-temperature circularly polarized superfluorescence, with emission intensity and polarization controllable by weak magnetic fields.
Nanomagnets control diamond qubits, pointing to more scalable quantum hardware
Nanomagnets control diamond qubits, pointing to more scalable quantum hardware Gaby Clark Scientific Editor Robert Egan Associate Editor Quantum computing, once only a theoretical possibility, promises to deliver faster, more energy-efficient computers—but only if scientists can build and scale the hardware needed to run the machines. New research from Virginia Commonwealth University brings scientists one small step closer to quantum computing at a practical scale, which could help...
There's already a way to mount your smartphone to a Steam Controller
There's already a way to mount your smartphone to a Steam Controller Mechanism, the company behind a "gaming pillow" for the Steam Deck and a growing list of grips for handheld consoles and PCs, already has its first Steam Controller accessory ready. Valve's new controller will be available to purchase on May 4, and that same day Mechanism will start selling the Basegrip for Steam Controller, an accessory that will let you attach the controller to a smartphone and plenty of other mounts the...
Radial and angular evolution of magnetic cloud signatures in the turbulent solar wind: virtual spacecraft analysis
arXiv:2606.07209v1 Announce Type: cross Abstract: Interplanetary coronal mass ejections (ICMEs) carry magnetic clouds (MCs), large-scale structures with average radial widths about a fifth of an astronomical unit at Earth's orbit. ICMEs display substructures in white light images and reveal rich dynamics across many spatial scales when directly measured by spacecraft. A spacecraft encounter with an ICME can result in smoothly rotating MC intervals or less organised magnetic obstacle (MO) ones.
