TL;DR: It is argued that the Griffiths singularity which has been proven to exist in dilute Ising magnets is an artifact of the thermodynamic limit procedure for finite macroscopically large samples, the behavior will be regular in most experimental samples while minute sample-dependent corrections, whose observability is uncertain, may appear in an exceedingly small fraction of real samples.

TL;DR: The efficiency and cooling power of a two-terminal thermoelectric refrigerator are analyzed near the limit of vanishing dissipation (ideal system), where the optimal efficiency is the Carnot one, but the cooling power vanishes.

TL;DR: In this paper, a model for phonons in disordered systems is proposed, and the authors use a percolation analysis to argue for a Debye spectrum at low frequencies for dimensions higher than one, and for a localization/delocalization transition (at a critical frequency) above two dimensions.

TL;DR: In this article, the magnetic response of a normal layer (N) coating a superconducting cylinder (S) is considered and the diamagnetic response of the normal layer is related to the formation of Andreev levels.

TL;DR: In this article, the authors considered the Landauer conductance G between two appropriate contacts of a one-dimensional (1D, single-channel) ring with elastic scatterers, and demonstrated analytically and numerically that upon averaging over an ensemble of different microscopic systems prepared under the same macroscopic conditions, the basic period of G(ensuremath{\varphi}) changes from
