Query: Holographic quenches and anomalous transport   In my master thesis, I investigated the chiral-magnetic effect in the context
of holography; I focused in especially on the impact of the chiral anomaly at
transport properties and non-equilbrium behaviour in response to an holographic
quench. Concretely, I considered an $U(1)_\text{A}\times
U(1)_\text{V}$-Einstein-Maxwell bottom-up model consisting of two massless
gauge fields, coupled by a Chern-Simons term in the fivedimensional AdS
spacetime. The two gauge fields provide a time dependent electric field and a
static magnetic field, parallel to it. As response of the system to quench, I
investigated the electromagnetic current in direction of the magnetic field
which is generated due to the CME. In the first part of the thesis, I
characterised the initial response of the system, in a fixed Schwarzschild AdS
background, subjected to a 'fast' quench. The corresponding hyperbolic PDE is
solved by means of a fully spectral code in spaces as well as in time
direction. Note that this was the first application of a fully spectral code
within holography. In the case of 'fast' quenches, the system exhibits an
universal scaling behaviour, independent of the external parameters as the
strength of the anomaly and the magnetic field, respectively. The late time
behaviour of the system shows, depending on the quench and external parameters,
in some cases long lived oscillations in the current. Furthermore, I computed
the quasi-normal modes of the systems, including the backreaction of the matter
fields on the background metric. It turns out that the long lived oscillations
appear only in presence of the anomaly and can be traced back to the presence
of Landau levels in the system. The results of my master thesis were partly
published in arXiv:1607.06817; however, the thesis contains a lot of
interesting, and so far unpublished, results and can be viewed as extended
version of the paper.
