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…
Modified heat equations for an analytic continuation of the spectral function
Tobias Zingg
For an elliptic differential operator of order in dimensions, the spectral -function for can be evaluated as an integral over the heat…
Planar Black holes and Entanglement Entropy in Analog Gravity Models
Neven Bilić, Tobias Zingg
Via constructing an explicit Lagrangian for which the perturbation equations are analogues of a scalar field propagating in a planar black hole space-time, it is found that all pla…
Holographic Response of Electron Clouds
Ulf Gran, Marcus Tornsö, Tobias Zingg
In order to make progress towards more realistic models of holographic fermion physics, we use gauge/gravity duality to compute the dispersion relations for quasinormal modes and c…
Analog Models for Holographic Transport
Sabine Hossenfelder, Tobias Zingg
The gauge-gravity duality and analog gravity both relate a condensed matter system to a gravitational theory. This makes it possible to use gravity as an intermediary to establish…
Exotic Holographic Dispersion
Ulf Gran, Marcus Tornsö, Tobias Zingg
For strongly interacting systems holographic duality is a powerful framework for computing e.g. dispersion relations to all orders in perturbation theory. Using the standard Reissn…
