On Holographic Defect Entropy
John Estes, Kristan Jensen, Andy O'Bannon +2
We study a number of (3+1)- and (2+1)-dimensional defect and boundary conformal field theories holographically dual to supergravity theories. In all cases the defects or boundaries…
Holographic Wilson Loops, Dielectric Interfaces, and Topological Insulators
John Estes, Andy O'Bannon, Efstratios Tsatis +1
We use holography to study (3+1)-dimensional N=4 supersymmetric SU(Nc) Yang-Mills theory (SYM) in the large-Nc and large coupling limits, with a (2+1)-dimensional interface where t…
Brane embeddings in sphere submanifolds
Nikos Karaiskos, Konstadinos Sfetsos, Efstratios Tsatis
Wrapping a D(8-p)-brane on AdS_2 times a submanifold of S^{8-p} introduces point-like defects in the context of AdS/CFT correspondence for a Dp-brane background. We classify and wo…
Mean Curvature Flow on Ricci Solitons
Efstratios Tsatis
We study monotonic quantities in the context of combined geometric flows. In particular, focusing on Ricci solitons as the ambient space, we consider solutions of the heat type equ…
