Anisotropic critical points from holography
Dimitrios Giataganas, Umut Gürsoy, Claire Moran +2
We present a comprehensive analysis of generic 5-dimensional Einstein-Maxwell-Dilaton-Axion (EMDA) holographic theories with exponential couplings. We find and classify exact, anal…
Quantum induced superradiance
Casey Cartwright, Umut Gürsoy, Juan F. Pedraza +1
Superradiance, the phenomenon enabling energy extraction through radiation amplification, is not universal to all black holes. We show that semi-classical backreaction can induce s…
Horizon universality and anomalous conductivities
Umut Gursoy, Javier Tarrio
We show that the value of chiral conductivities associated with anomalous transport is universal in a general class of strongly coupled quantum field theories. Our result applies t…
(Non)renormalization of Anomalous Conductivities and Holography
Umut Gursoy, Aron Jansen
The chiral magnetic and the chiral vortical effects are recently discovered phenomena arising from chiral gauge and gravitational anomalies that lead to generation of electric curr…
Continuous Hawking-Page transitions in Einstein-scalar gravity
Umut Gursoy
We investigate continuous Hawking-Page transitions in Einstein's gravity coupled to a scalar field with an arbitrary potential in the weak gravity limit. We show that this is only…
Improved Holographic QCD
Umut Gürsoy, Elias Kiritsis, Liuba Mazzanti +2
We provide a review to holographic models based on Einstein-dilaton gravity with a potential in 5 dimensions. Such theories, for a judicious choice of potential are very close to t…
