TLDR
In this paper, a wide range of experimental and theoretical studies of two-level or tunnelling states in glasses are discussed, focusing on fundamental physics rather than a detailed comparison of experiment and theory.
Abstract
This review covers a wide range of experimental and theoretical studies of two-level or tunnelling states in glasses. Emphasis is on fundamental physics rather than a detailed comparison of experiment and theory. Sections cover the static and dynamic properties of tunnelling states, their contribution to thermal properties and their response to weak and strong electric and acoustic fields, both steady state and pulsed. A section on metallic glasses focuses on the importance of electron tunnelling-state interactions, and a final section illustrates approaches to a microscopic description by means of selected examples.

Quantum mechanics

TL;DR: The blackbody radiation problem was solved by Max Planck as mentioned in this paper, who showed that radiation was not continuous but discrete, coming in lumps known as quanta, which became known as Planck's constant and led to the correct prediction of the blackbody spectrum.

Anomalous low-temperature thermal properties of glasses and spin glasses

TL;DR: In this article, a linear specific heat at low temperatures for glass follows naturally from general considerations on the glassy state, and the experimentally observed anomalous low-temperature thermal conductivity is predicted.

Tunneling states in amorphous solids

TL;DR: In this paper, a linear temperature dependence of the specific heat in amorphous solids at very low temperatures is shown to follow from an ionic tunneling model, which predicts both the observed temperature dependence and the magnitude of the thermal conductivity.
