Supersolidity of glasses

TL;DR

This paper explains supersolidity in glasses as a unique condensed matter state involving mass transfer via tunneling two-level systems, distinct from normal and superfluid solids.

Contribution

It introduces a novel explanation for supersolidity in glasses based on tunneling two-level systems as the underlying mechanism.

Findings

Supersolidity arises from tunneling two-level systems.

The state is fundamentally different from normal and superfluid solids.

Mass transfer occurs through quantum tunneling processes.

Abstract

Supersolidity of glasses is explained as a property of an unusual state of condensed matter. This state is essentially different from both normal and superfluid solid states. The mechanism of the phenomenon is the transfer of mass by tunneling two level systems.
