Extreme Fragility of Local Structure of Metallic Glasses


Molecular dynamics (MD) simulations show that the energy barriers separating nearly degenerate states in metallic glasses are low, and easily overcome by quantum fluctuations.

It is widely assumed that atoms are frozen and immobile in a glass. However, simulation shows atoms are locally moving through thermal and quantum fluctuations.
