Strings from interacting quantum fields
Domingo Gallegos, Umut Gursoy, Natale Zinnato
We generalize Gopakumar's microscopic derivation of Witten diagrams in large N free quantum field theory [1] to interacting theories in perturbative expansion. For simplicity we co…
Holographic QCD and magnetic fields
Umut Gursoy
We review the holographic approach to electromagnetic phenomena in large N QCD. After a brief discussion of existing holographic models, we concentrate on the improved holographic…
Hydrodynamics of spin currents
Domingo Gallegos, Umut Gursoy, Amos Yarom
We study relativistic hydrodynamics in the presence of a non vanishing spin chemical potential. Using a variety of techniques we carry out an exhaustive analysis, and identify the…
Dynamical gauge fields and anomalous transport at strong coupling
Angel Domingo Gallegos, Umut Gürsoy
Anomalous transport coefficients are known to be universal in the absence of dynamical gauge fields. We calculate the corrections to these universal values due to dynamical gluon f…
Improved Holographic QCD and the Quark-gluon Plasma
Umut Gursoy
We review construction of the improved holographic models for QCD-like confining gauge theories and their applications to the physics of the Quark-gluon plasma. We also review rece…
A magnetically induced quantum phase transition in holography
A. Gnecchi, U. Gursoy, O. Papadoulaki +1
We investigate quantum phase transitions in a 2+1 dimensional gauge theory at finite chemical potential and magnetic field . The gravity dual is based on 4D …
