    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 ...

    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, ...
