A new unified theory connects two fundamental domains of modern quantum physics: It joins two opposite views of how a single ...

When quantum spins interact, they can produce collective behaviors that defy long-standing expectations. Researchers have now shown that the Kondo effect behaves very differently depending on spin ...

Record-breaking experiment shows that a cluster of thousands of atoms can act like a wave as well as a particle.

Collective behavior is an unusual phenomenon in condensed-matter physics. When quantum spins interact together as a system, ...

Quantum materials can behave in surprising ways when many tiny spins act together, producing effects that don’t exist in ...

Electronic order in quantum materials often emerges not uniformly, but through subtle and complex patterns that vary from ...
