Radiating black holes in Einstein-Maxwell-dilaton theory and cosmic censorship violation
Pedro Aniceto, Paolo Pani, Jorge V. Rocha
We construct exact, time-dependent, black hole solutions of Einstein-Maxwell-dilaton theory with arbitrary dilaton coupling, . For this theory arises as the four-dimension…
Black holes and the multiverse
Jaume Garriga, Alexander Vilenkin, Jun Zhang
Vacuum bubbles may nucleate and expand during the inflationary epoch in the early universe. After inflation ends, the bubbles quickly dissipate their kinetic energy; they come to r…
Three-dimensional super Yang-Mills with compressible quark matter
Antón F. Faedo, Arnab Kundu, David Mateos +2
We construct the gravity dual of three-dimensional, super Yang-Mills theory with flavors of dynamical quarks in the presence of a non-zero qua…
Probing N=2 superconformal field theories with localization
Bartomeu Fiol, Blai Garolera, Genis Torrents
We use supersymmetric localization to study probes of four dimensional Lagrangian N=2 superconformal field theories. We first derive a unique equation for the eigenvalue density of…
The Exact Bremsstrahlung Function in N=2 Superconformal Field Theories
Bartomeu Fiol, Efrat Gerchkovitz, Zohar Komargodski
We propose an exact formula for the energy radiated by an accelerating quark in N=2 superconformal theories in four dimensions. This formula reproduces the known Bremsstrahlung fun…
Tree-Level Unitarity and Renormalizability in Lifshitz Scalar Theory
Toshiaki Fujimori, Takeo Inami, Keisuke Izumi +1
We study unitarity and renormalizability in the Lifshitz scalar field theory, which is characterized by an anisotropic scaling between the space and time directions. Without the Lo…
