New Horizons for Black Holes and Branes
Roberto Emparan, Troels Harmark, Vasilis Niarchos +1
We initiate a systematic scan of the landscape of black holes in any spacetime dimension using the recently proposed blackfold effective worldvolume theory. We focus primarily on a…
Brane Dynamics and 3D Seiberg Duality on the Domain Walls of 4D N=1 SYM
Adi Armoni, Amit Giveon, Dan Israel +1
We study a three-dimensional U(k) Yang-Mills Chern-Simons theory with adjoint matter preserving two supersymmetries. According to Acharya and Vafa, this theory describes the low-en…
R-charges, Chiral Rings and RG Flows in Supersymmetric Chern-Simons-Matter Theories
Vasilis Niarchos
We discuss the non-perturbative behavior of the U(1)_R symmetry in N=2 superconformal Chern-Simons theories coupled to matter in the (anti)fundamental and adjoint representations o…
World-Volume Effective Theory for Higher-Dimensional Black Holes
Roberto Emparan, Troels Harmark, Vasilis Niarchos +1
We argue that the main feature behind novel properties of higher-dimensional black holes, compared to four-dimensional ones, is that their horizons can have two characteristic leng…
Multi-String Theories, Massive Gravity and the AdS/CFT Correspondence
Vasilis Niarchos
Infrared modifications of gravity have been proposed over the years as potentially useful phenomenological models. Massive (multi)-gravity is an interesting class of such theories.…
