Heterotic String Theory Suggests a QCD Axion Near 0.5 neV
Joshua N. Benabou, Giulio Alvise Dainelli, Mario Reig +1
We show that in heterotic string theory -- and dual corners of the landscape including Type I string theory -- the QCD axion mass is bounded from below by neV, a…
Renyi entropy, stationarity, and entanglement of the conformal scalar
Jeongseog Lee, Aitor Lewkowycz, Eric Perlmutter +1
We extend previous work on the perturbative expansion of the Renyi entropy, , around for a spherical entangling surface in a general CFT. Applied to conformal scalar fie…
Renyi Entropy and Geometry
Jeongseog Lee, Lauren McGough, Benjamin R. Safdi
Entanglement entropy in even dimensional conformal field theories (CFTs) contains well-known universal terms arising from the conformal anomaly. Renyi entropies are natural general…
Higher Spin AdS/CFT at One Loop
Simone Giombi, Igor R. Klebanov, Benjamin R. Safdi
Following arXiv:1308.2337, we carry out one loop tests of higher spin AdS/CFT correspondences for . The Vasiliev theories in AdS, which contain each in…
AdS Description of Induced Higher-Spin Gauge Theory
Simone Giombi, Igor R. Klebanov, Silviu S. Pufu +2
We study deformations of three-dimensional large N CFTs by double-trace operators constructed from spin s single-trace operators of dimension Δ. These theories possess UV fixed poi…
A Crack in the Conformal Window
Benjamin R. Safdi, Igor R. Klebanov, Jeongseog Lee
In {\cal N} = 2 superconformal three-dimensional field theory the R-symmetry is determined by locally maximizing the free energy F on the three-sphere. Using F-maximization, we stu…
