Holographic Calculation of Boundary Entropy
Tatsuo Azeyanagi, Andreas Karch, Tadashi Takayanagi +1
We use the holographic proposal for calculating entanglement entropies to determine the boundary entropy of defects in strongly coupled two-dimensional conformal field theories. We…
Holographic Thermodynamics at Finite Baryon Density: Some Exact Results
Andreas Karch, Andy O'Bannon
We use the AdS/CFT correspondence to study the thermodynamics of massive N=2 supersymmetric hypermultiplets coupled to N=4 supersymmetric SU(Nc) Yang-Mills theory in the limits of…
Time dependent black holes and thermal equilibration
Dongsu Bak, Michael Gutperle, Andreas Karch
We study aspects of a recently proposed exact time dependent black hole solution of IIB string theory using the AdS/CFT correspondence. The dual field theory is a thermal system in…
Metallic AdS/CFT
Andreas Karch, Andy O'Bannon
We use the AdS/CFT correspondence to compute the conductivity of massive N=2 hypermultiplet fields at finite baryon number density in an N=4 SU(N_c) super-Yang-Mills theory plasma…
Debye screening in strongly coupled N=4 supersymmetric Yang-Mills plasma
Dongsu Bak, Andreas Karch, Laurence G. Yaffe
Using the AdS/CFT correspondence, we examine the behavior of correlators of Polyakov loops and other operators in N=4 supersymmetric Yang-Mills theory at non-zero temperature. The…
