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 ...

The size of the spin crucially affects how the system behaves. At spin-1/2, fully quantum spins pair up and cancel each other ...

A new kind of mirror is emerging from quantum physics labs, one that exists not as a chunk of polished glass but as a ...
