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…
Extremal isosystolic metrics with multiple bands of crossing geodesics
Usman Naseer, Barton Zwiebach
We apply recently developed convex programs to find the minimal-area Riemannian metric on -sided polygons () with length conditions on curves joining opposite sides. W…
Gauge theories on spheres with 16 supercharges and non-constant couplings
Joseph A. Minahan, Usman Naseer
We construct a class of theories with 16 supersymmetries on spheres of dimension nine and less. The gauge coupling and mass terms for the scalar fields depend on the polar angle aw…
(1,0) gauge theories on the six-sphere
Usman Naseer
We construct gauge theories with a vector-multiplet and hypermultiplets of supersymmetry on the six-sphere. The gauge coupling on the sphere depends on the polar angle. Thi…
A note on large gauge transformations in double field theory
Usman Naseer
We give a detailed proof of the conjecture by Hohm and Zwiebach in double field theory. This result implies that their proposal for large gauge transformations in terms of the Jaco…
