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

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 ...

Quantum physics didn’t set out to explain the mind. It set out to explain matter. And yet, the deeper scientists went into ...
