Extended First Law for Entanglement Entropy in Lovelock Gravity

  title={Extended First Law for Entanglement Entropy in Lovelock Gravity},
  author={David Kastor and Sourya Ray and Jennie Traschen},
The first law for the holographic entanglement entropy of spheres in a boundary CFT with a bulk Lovelock dual is extended to include variations of the bulk Lovelock coupling constants. Such variations in the bulk correspond to perturbations within a family of boundary CFTs. The new contribution to the first law is found to be the product of the variation $\delta a$ of the A-type trace anomaly coefficient for even dimensional CFTs, or more generally its extension $\delta a^*$ to include odd… CONTINUE READING
