A smeared quantum phase transition in disordered holography
Martin Ammon, Matteo Baggioli, Amadeo Jiménez-Alba +1
We study the effects of quenched one-dimensional disorder on the holographic Weyl semimetal quantum phase transition (QPT), with a particular focus on the quantum critical region.…
Holographic Phonons
Lasma Alberte, Martin Ammon, Matteo Baggioli +2
We present a class of holographic massive gravity models that realize a spontaneous breaking of translational symmetry - they exhibit transverse phonon modes whose speed relates to…
Surface States in Holographic Weyl Semimetals
Martin Ammon, Markus Heinrich, Amadeo Jiménez-Alba +1
We study the surface states of a strongly coupled Weyl semimetal within holography. By explicit numerical computation of an inhomogeneous holographic Weyl semimetal we observe the…
Holographic quenches and anomalous transport
Martin Ammon, Sebastian Grieninger, Amadeo Jimenez-Alba +2
We study the response of the chiral magnetic effect due to continuous quenches induced by time dependent electric fields within holography. Concretely, we consider a holographic mo…
Anomalous magnetoconductivity and relaxation times in holography
Amadeo Jimenez-Alba, Karl Landsteiner, Yan Liu +1
We study the magnetoconductivity induced by the axial anomaly via the chiral magnetic effect in strongly coupled holographic models. An important ingredient in our models is that t…
Second Order Transport Coefficient from Chiral Anomaly at Weak Coupling: Diagrammatic Resummation
Amadeo Jimenez-Alba, Ho-Ung Yee
We compute one of the second order transport coefficients arising from the chiral anomaly in a high temperature weakly coupled regime of quark-gluon plasma. This transport coeffici…
Anomalous Magneto Response and the Stückelberg Axion in Holography
Amadeo Jimenez-Alba, Karl Landsteiner, Luis Melgar
We study the magneto response with non-conserved currents in Holography. Non-conserved currents are dual to massive vector fields in AdS. We introduce the mass in a gauge invariant…
Anomalous Transport in Holographic Chiral Superfluids via Kubo Formulae
Amadeo Jimenez-Alba, Luis Melgar
We study anomalous conductivities in Chiral Superfluids in the framework of two different holographic models, by means of Kubo formulae. In addition, we point out the existence of…
Holographic s+p Superconductors
Irene Amado, Daniel Arean, Amadeo Jimenez-Alba +2
We study the phase diagram of a holographic model realizing a U(2) global symmetry on the boundary and show that at low temperature a phase with both scalar s and vector p condensa…
Holographic Superfluids and the Landau Criterion
Irene Amado, Daniel Arean, Amadeo Jimenez-Alba +3
We revisit the question of stability of holographic superfluids with finite superfluid velocity. Our method is based on applying the Landau criterion to the Quasinormal Mode (QNM)…
Holographic Type II Goldstone bosons
Irene Amado, Daniel Arean, Amadeo Jimenez-Alba +3
The Goldstone theorem implies the appearance of an ungapped mode whenever a continuous global symmetry is spontaneously broken. In general it does not say anything about the precis…
