Deconfinement and Thermodynamics in 5D Holographic Models of QCD
Umut Gursoy
We review 5D holographic approaches to finite temperature QCD. Thermodynamic properties of the "hard-wall" and the "soft-wall" models are derived. Various non-realistic features in…
Probing Universality in the Gravity Duals of N=1 SYM by gamma-deformations
Umut Gursoy
Recently, a one-parameter deformation of the Maldacena-Nunez dual of the N=1 SYM theory was constructed in hep-th/0505100. According to the Lunin-Maldacena conjecture, the backgrou…
Comments on the beta-deformed N=4 SYM Theory
Daniel Z. Freedman, Umut Gursoy
Several calculations of 2- and 3-point correlation functions in the deformed theory are presented. The central charge in the Lunin-Maldacena gravity dual is shown to be independent…
Dipole Deformations of N=1 SYM and Supergravity backgrounds with U(1) X U(1) global symmetry
Umut Gursoy, Carlos Nunez
We study SL(3,R) deformations of a type IIB background based on D5 branes that is conjectured to be dual to N=1 SYM. We argue that this deformation of the geometry correspond to tu…
The chiral anomaly from M theory
Umut Gursoy, Sean A. Hartnoll, Ruben Portugues
We argue that the chiral anomaly of $\Ncal = 1$ super Yang-Mills theory admits a dual description as spontaneous symmetry breaking in M theory on holonomy manifolds. We ident…
Instability and Degeneracy in the BMN Correspondence
Daniel Z. Freedman, Umut Gursoy
Non-degenerate perturbation theory, which was used to calculate the scale dimension of operators on the gauge theory side of the correspondence, breaks down when effects of triple…
