Hyperscaling violation from supergravity
Eric Perlmutter
In recent applications of AdS/CFT to condensed matter physics, a metric that transforms covariantly under dilatation has been argued to signal hyperscaling violation in a dual quan…
Growing Extra Dimensions in AdS/CFT
Luis F. Alday, Eric Perlmutter
What is the dimension of spacetime? We address this question in the context of the AdS/CFT Correspondence. We give a prescription for computing the number of large bulk dimensions,…
Unitarity Methods in AdS/CFT
David Meltzer, Eric Perlmutter, Allic Sivaramakrishnan
We develop a systematic unitarity method for loop-level AdS scattering amplitudes, dual to non-planar CFT correlators, from both bulk and boundary perspectives. We identify cut ope…
General Results for Higher Spin Wilson Lines and Entanglement in Vasiliev Theory
Ashwin Hegde, Per Kraus, Eric Perlmutter
We develop tools for the efficient evaluation of Wilson lines in 3D higher spin gravity, and use these to compute entanglement entropy in the hs Vasiliev theory that governs…
Genus-One String Amplitudes from Conformal Field Theory
Luis F. Alday, Agnese Bissi, Eric Perlmutter
We explore and exploit the relation between non-planar correlators in super-Yang-Mills, and higher-genus closed string amplitudes in type IIB string theory. By conform…
Discreteness and Integrality in Conformal Field Theory
Justin Kaidi, Eric Perlmutter
Various observables in compact CFTs are required to obey positivity, discreteness, and integrality. Positivity forms the crux of the conformal bootstrap, but understanding of the a…
