Anomalous diffusion and Noether's second theorem
Matteo Baggioli, Gabriele La Nave, Philip W. Phillips
Despite the fact that conserved currents have dimensions that are determined solely by dimensional analysis (and hence no anomalous dimensions), Nature abounds in examples of anoma…

Transverse Collective Modes in Interacting Holographic Plasmas
Matteo Baggioli, Ulf Gran, Marcus Tornsö
We study in detail the transverse collective modes of simple holographic models in presence of electromagnetic Coulomb interactions. We render the Maxwell gauge field dynamical via…

Holographic Plasmon Relaxation with and without Broken Translations
Matteo Baggioli, Ulf Gran, Amadeo Jimenez Alba +2
We study the dynamics and the relaxation of bulk plasmons in strongly coupled and quantum critical systems using the holographic framework. We analyze the dispersion relation of th…
