Notes on entanglement entropy for excites holographic states in 2d

Understand

In this work we revisit the problem of contributions of excited holographic states to the entanglement entropy in two-dimensional conformal field theories.

• Using the results of replica trick method we find three expressions for these contributions.
• First, we express the contribution of the excited states in terms of Aharonov invariants.
• It is shown that beside the Schwarzian, the one-point functions of descendants of energy-momentum also contribute.
