quantum glassiness

Quantum glassiness refers to a state where a material remains in a disordered, non-crystalline formation and resists reaching equilibrium, even at very low temperatures. Unlike typical solids that crystallize, these materials have complex quantum interactions that create energetic barriers, preventing them from "settling" into a stable state. As a result, they exhibit extremely slow dynamics and can stay "frozen" in a non-equilibrium condition for long periods. This behavior is significant in understanding certain exotic states of matter and can impact how quantum materials are used in technology, such as quantum computing.
