    Conductivities from attractors 
    Erdmenger, Johanna; Fernández, Daniel; Goulart, Prieslei; Witkowski, Piotr (Springer Nature, 2017-03)
    In the context of applications of the AdS/CFT correspondence to condensed matter physics, we compute conductivities for field theory duals of dyonic planar black holes in 3+1-dimensional Einstein-Maxwell-dilaton theories at zero temperature. We ...

    A cornucopia of AdS5 vacua 
    Bobev, Nikolay; Fischbacher, Thomas; Gautason, Fridrik F; Pilch, Krzysztof (Springer Science and Business Media LLC, 2020-07-01)
    We report on a systematic search for AdS5 vacua corresponding to critical points of the potential in the five-dimensional N = 8 SO(6) gauged supergravity. By employing Google’s TensorFlow Machine Learning library, we find the total of 32 critical points ...

    Generalised global symmetries in holography: magnetohydrodynamic waves in a strongly interacting plasma 
    Grozdanov, Sašo; Poovuttikul, Napat (Springer Science and Business Media LLC, 2019-04-23)
    We begin the exploration of holographic duals to theories with generalised global (higher-form) symmetries. In particular, we focus on the case of magnetohydrodynamics (MHD) in strongly coupled plasmas by constructing and analysing a holographic dual ...

    Time evolution of entanglement for holographic steady state formation 
    Erdmenger, Johanna; Fernández, Daniel; Flory, Mario; Megías, Eugenio; Straub, Ann-Kathrin; Witkowski, Piotr (Springer Nature, 2017-10)
    Within gauge/gravity duality, we consider the local quench-like time evolution obtained by joining two 1+1-dimensional heat baths at different temperatures at time t = 0. A steady state forms and expands in space. For the 2+1-dimensional gravity dual, ...
