Entanglement Entropy of Extremal BTZ
Pawel Caputa, Vishnu Jejjala, Hesam Soltanpanahi
In this note, we use entanglement entropy as a tool to explore the universal properties of CFTs dual to extremal BTZ black holes. We demonstrate that the entanglement entropies com…
Dynamical entanglement entropy with angular momentum and U(1) charge
Pawel Caputa, Gautam Mandal, Ritam Sinha
We consider time-dependent entanglement entropy (EE) for a 1+1 dimensional CFT in the presence of angular momentum and U(1) charge. The EE saturates, irrespective of the initial st…
Cosmology or Catastrophe? A non-minimally coupled scalar in an inhomogeneous universe
Pawel Caputa, Sheikh Shajidul Haque, Joseph Olson +1
A non-minimally coupled scalar field can have, in principle, a negative effective Planck mass squared which depends on the scalar field. Surprisingly, an isotropic and homogeneous…
Operators, Correlators and Free Fermions for SO(N) and Sp(N)
Pawel Caputa, Robert de Mello Koch, Pablo Diaz
Using the recently constructed basis for local operators in free SO(N) gauge theory we derive an exact formula for the correlation functions of multi trace operators. This formula…
A basis for large operators in N=4 SYM with orthogonal gauge group
Pawel Caputa, Robert de Mello Koch, Pablo Diaz
We develop techniques to study the correlation functions of "large operators" whose bare dimension grows parametrically with N, in SO(N) gauge theory. We build the operators from a…
