Conformal field theories on deformed spheres, anomalies, and supersymmetry
Joseph A. Minahan, Usman Naseer, Charles Thull
We study the free energy of four-dimensional CFTs on deformed spheres. For generic nonsupersymmetric CFTs only the coefficient of the logarithmic divergence in the free energy is p…

Entanglement Entropy in Closed String Theory
Usman Naseer
In local quantum field theory, the entanglement entropy of a region is divergent due to the arbitrary short-wavelength correlations near the boundary of the region. Quantum gravita…
