Collective modes of polarizable holographic media in magnetic fields
Matteo Baggioli, Ulf Gran, Marcus Tornsö
We consider a neutral holographic plasma with dynamical electromagnetic interactions in a finite external magnetic field. The Coulomb interactions are introduced via mixed boundary…
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 fundamental matter in multilayered media
Ulf Gran, Niko Jokela, Daniele Musso +2
We describe a strongly coupled layered system in 3+1 dimensions by means of a top-down D-brane construction. Adjoint matter is encoded in a large- stack of D3-branes, while fu…
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…
Plasmons in Holographic Graphene
Ulf Gran, Marcus Tornsö, Tobias Zingg
We demonstrate how self-sourced collective modes - of which the plasmon is a prominent example due to its relevance in modern technological applications - are identified in strongl…
