Electronic Sound and Diffusion in Disordered Multiband Metals
Miguel-Ãngel Sánchez-MartÃnez, Blaise Goutéraux, Louk Rademaker +1
Multiband metals can host acoustic plasmons: gapless collective charge excitations involving out-of-phase motion of electrons in different bands, sometimes referred to as 'demons'.…

Fractal Topology of Majorana Bound States in Superconducting Quasicrystals
William Caiger, Felix Flicker, Miguel-Ãngel Sánchez-MartÃnez
Quasicrystalline order induces a fractal energy spectrum, yet its impact on topological protection remains an open fundamental question. Here, we demonstrate that the topological p…

Power spectrum of magnetic relaxation in spin ice: anomalous diffusion in a Coulomb fluid
D. Billington, E. Riordan, C. Cafolla-Ward +7
Magnetization noise measurements on the spin ice DyTiO have revealed a remarkable `pink noise' power spectrum below 4 K, including evidence of magnetic m…
