Hidden, entangled and resonating order

TL;DR

This paper discusses hidden, entangled, and resonating orders in condensed matter systems, highlighting their elusive nature and the potential for discovering new complex orders beyond conventional detection methods.

Contribution

It provides an overview of known hidden orders and emphasizes the possibility of uncovering more complex, entangled, or dynamical hidden orders in condensed matter physics.

Findings

Hidden orders can lead to unexpected properties in materials.

Conventional probes often fail to detect these hidden orders.

Future research may reveal more complex hidden orders.

Abstract

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.
