Reply to Chakrabarty et al.: Particles move even in ideal glasses

TL;DR

This paper discusses the ongoing debate about particle mobility in ideal glasses, emphasizing that particles continue to move even in these supposedly rigid states, challenging traditional views.

Contribution

It provides a response to prior claims, reaffirming that particle motion persists in ideal glasses and clarifies misunderstandings in the field.

Findings

Particles exhibit movement in ideal glass states

Challenges the notion of complete rigidity in glasses

Supports ongoing research on glass dynamics
