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…

Optical probes of two-component pairing states in transition metal dichalcogenides
Miguel-Ãngel Sánchez-MartÃnez, Daniel Muñoz-Segovia, Fernando de Juan
Signatures of unconventional superconductivity have been recently observed in certain transition metal dichalcogenides (TMDs), including 4H-TaS and monolayer 2H-NbSe. W…
