On the Architecture of Spacetime Geometry
Eugenio Bianchi, Robert C. Myers
We propose entanglement entropy as a probe of the architecture of spacetime in quantum gravity. We argue that the leading contribution to this entropy satisfies an area law for any…
Horizons cannot save the Landscape
Iosif Bena, Alex Buchel, Oscar J. C. Dias
Solutions with anti-D3 branes in a Klebanov-Strassler geometry with positive charge dissolved in fluxes have a certain singularity corresponding to a diverging energy density of th…
Dynamics of holographic thermalization
Walter H. Baron, Damian Galante, Martin Schvellinger
Dynamical evolution of thin shells composed by different kinds of degrees of freedom collapsing within asymptotically AdS spaces is explored with the aim of investigating models of…
Neutron-star mergers in scalar-tensor theories of gravity
Enrico Barausse, Carlos Palenzuela, Marcelo Ponce +1
Scalar-tensor theories of gravity are natural phenomenological alternatives to General Relativity, where the gravitational interaction is mediated by a scalar degree of freedom, be…
Quantized topological terms in weak-coupling gauge theories with symmetry and their connection to symmetry enriched topological phases
Ling-Yan Hung, Xiao-Gang Wen
We study the quantized topological terms in a weak-coupling gauge theory with gauge group and a global symmetry in space-time dimensions. We show that the quantized…
Jet Launching Structure Resolved Near the Supermassive Black Hole in M87
Sheperd S. Doeleman, Vincent L. Fish, David E. Schenck +30
Approximately 10% of active galactic nuclei exhibit relativistic jets, which are powered by accretion of matter onto super massive black holes. While the measured width profiles of…
