Hidden, entangled and resonating order

Nature Reviews Materials volume 5, pages 477–479 (2020)Cite this article

Subjects

In condensed matter systems, the atoms, electrons or spins can sometimes arrange themselves in ways that result in unexpected properties but that cannot be detected by conventional experimental probes. Several historical and contemporary examples of such hidden orders are known and more are awaiting discovery, perhaps in the form of more complex composite, entangled or dynamical hidden orders.
