Researchers have achieved a major breakthrough by generating quantum spin currents in graphene—without relying on bulky magnetic fields. By pairing graphene with a magnetic material, they unlocked a ...

Using ultracold atoms and laser light, researchers recreated the behavior of a Josephson junction—an essential component of quantum computers and voltage standards. The appearance of Shapiro steps in ...

In a novel experiment, physicists have observed long range quantum coherence effects due to Aharonov-Bohm interference in a topological insulator-based device. This finding opens up a new realm of ...

Quantum effects are fundamental in shaping the behaviour of molecular systems, from modifying reaction pathways to influencing physical properties. At the molecular scale, classical theories are often ...

Collective behavior is an unusual phenomenon in condensed-matter physics. When quantum spins interact together as a system, they produce unique effects not seen in individual particles. Understanding ...
