Floquet-Anderson localization in the Thouless pump and how to avoid it

András Grabarits, Attila Takács, Ion Cosma Fulga +1

We investigate numerically how onsite disorder affects conduction in the periodically driven Rice-Mele model, a prototypical realization of the Thouless pump. Although the pump is…

Acoustic properties of metallic glasses at low temperatures -- tunneling systems and their dephasing

Arnold Meißner, Tim Voigtländer, Saskia M. Meißner +4

The low temperature acoustic properties of bulk metallic glasses measured over a broad range of frequencies rigorously test the predictions of the standard tunneling model. The str…

The metal-insulator transition in disordered solids: How theoretical prejudices influence its characterization. A critical review of analyses of experimental data

A. Mobius

In a recent experiment, Siegrist et al. [Nature Materials 10, 202 (2011)] investigated the metal-insulator transition (MIT) of GeSb_2Te_4 on increasing annealing temperature. The a…

Disordered magnetism in superconducting KFe2As2 single crystals

V. Grinenko, S. -L. Drechsler, M. Abdel-Hafiez +10

High-quality KFe2As2 (K122) single crystals synthesized by different techniques have been studied by magnetization and specific heat (SH) measurements. There are 2 types of samples…
