A theory of phonon-mediated superconductivity in strong-coupling amorphous materials is developed based on an effective description of structural disorder and its effect on the vibrational spectrum. The theory accounts for the diffusivelike transport of vibrational excitations due to disorder-induced scattering within the Eliashberg theory of strong-coupling superconductivity. The theory provides a good analytical description of the Eliashberg function ${\ensuremath{\alpha}}^{2}F(\ensuremath…

Anharmonic phonon damping enhances theTcof BCS-type superconductors

A theory of superconductivity is presented where the effect of anharmonicity, as entailed in the acoustic, or optical, phonon damping, is explicitly considered in the pairing mechanism. The gap

It is argued that superconductivity of n-doped SrTiO3 results from the interaction of electrons with several longitudinal (LO) optical phonons with frequencies much larger than the Fermi energy.

Universal link between the boson peak and transverse phonons in glass.

This work discovered evidence suggestive of the equality of the boson peak frequency to the Ioffe-Regel limit for 'transverse' phonons, above which transverse phonons no longer propagate, and suggested a possible link between slow structural relaxation and fast bosonpeak dynamics in glass-forming systems.

Unified theory of vibrational spectra in hard amorphous materials

The phonon spectra of solids, described through the measurable vibrational density of states (VDOS), provide a wealth of information about the underlying atomic structure and bonding, and they

Glass-induced enhancement of superconducting Tc : Pairing via dissipative mediators

With substantial evidence of glassy behavior in the phase diagram of high $T_c$ superconductors and its co-existence with superconductivity, we attempt to answer the question: what are the properties

Disorder-induced multifractal superconductivity in monolayer niobium dichalcogenides

The interplay between disorder and superconductivity is a subtle and fascinating phenomenon in quantum many-body physics. Conventional superconductors are insensitive to dilute non-magnetic

Evidence of High Frequency Propagating Modes in Vitreous Silica.

The existence of collective modes in the whole investigated Q range is reported, suggesting that the peaks broadening is not associated with dynamical processes, but to the ill-definition of Q as a good quantum number.

Nonmagnetic impurities change the electron-phonon interaction in a metal and therefore they influence the superconducting properties. This is demonstrated for an impure simple metal by deriving the
