Stringy NJL and Gross-Neveu models at finite density and temperature
Joshua L. Davis, Michael Gutperle, Per Kraus +1
Nonlocal stringy versions of the Nambu-Jona-Lasinio and Gross-Neveu models arise in a certain limit of holographic QCD. We analyze the phase structure at finite density and tempera…
Fundamental Strings, Holography, and Nonlinear Superconformal Algebras
Per Kraus, Finn Larsen, Akhil Shah
We discuss aspects of holography in the AdS_3 \times S^p near string geometry of a collection of straight fundamental heterotic strings. We use anomalies and symmetries to determin…
Precision Entropy of Spinning Black Holes
Alejandra Castro, Joshua L. Davis, Per Kraus +1
We construct spinning black hole solutions in five dimensions that take into account the mixed gauge-gravitational Chern-Simons term and its supersymmetric completion. The resultin…
5D Black Holes and Strings with Higher Derivatives
Alejandra Castro, Joshua L. Davis, Per Kraus +1
We find asymptotically flat black hole and string solutions to 5D supergravity in the presence of higher derivative terms. In some cases, including the fundamental heterotic string…
5D Attractors with Higher Derivatives
Alejandra Castro, Joshua L. Davis, Per Kraus +1
We analyze higher derivative corrections to attractor geometries in five dimensions. We find corrected AdS_3xS^2 geometries by solving the equations of motion coming from a recentl…
