A theoretical study suggests black holes could evade singularities when electric charge interacts with Hawking radiation, reshaping ideas about spacetime collapse.

The research proposes quantum effects inside charged black holes may prevent infinite density formation, potentially resolving one of physics’ deepest paradoxes.

Researchers show quantum many-body scrambling generates multipartite entanglement for enhanced sensing. Chaotic interactions spread correlations across many particles, producing highly entangled resources from simple states.

This entanglement boosts measurement precision beyond classical limits, directly linking quantum chaos and information scrambling to improved metrological performance in many-body systems.

This study demonstrates control over the knot topology of magnetic hopfions using spin–orbit torque, enabling manipulation of their internal topological structure.

The work shows that electric currents can reconfigure these stable 3D magnetic textures, offering a route toward topological spintronic devices and information encoding schemes.
