Type-I clathrate compounds have attracted a great deal of interest in connection with the
search for efficient thermoelectric materials. These compounds constitute networked cages …

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 …

Dielectric loss from two-level states is shown to be a dominant decoherence source in
superconducting quantum bits. Depending on the qubit design, dielectric loss from …

The glass transition is well known to glass makers or from the common ex perience of drying
a used chewing gum. A liquid melt or a rubber becomes a solid glass when its temperature …

In dielectric solids, most of the thermal energy is contained in the form of lattice vibrations,
which, therefore, play an essential role in all processes that involve temperature. The …

Suitable for researchers and graduate students in physics and material science," Physical
Acoustics in the Solid State" reviews the modern aspects in the field, including many …

The microwave performance of amorphous dielectric materials at very low temperatures and
very low excitation strengths displays significant excess loss. Here, we present the loss …

We examine the vibrational spectrum of a glass of soft spheres produced by quenching an
equilibrated liquid (produced via constant-energy molecular-dynamics simulation) to zero …

We present a new method to measure 1/f noise in Josephson quantum bits (qubits) that
yields low-frequency spectra below 1 Hz. A comparison of the noise taken at positive and …

We study spectral and wave-function statistics for many-body localization transition in
systems with long-range interactions decaying as 1/r α with an exponent α satisfying d≤ α≤ …
