# Note On The Dilaton Effective Action And Entanglement Entropy

@article{Banerjee2014NoteOT, title={Note On The Dilaton Effective Action And Entanglement Entropy}, author={Shamik Banerjee}, journal={arXiv: High Energy Physics - Theory}, year={2014} }

In this note we do the analysis of entanglement entropy more carefully when the non-conformal theory flows to a non-trivial IR fixed point. In particular we emphasize the role of the trace of the energy-momentum tensor in these calculations. We also compare the current technique for evaluating the entanglement entropy, particularly the Green's function method for gaussian theories, with the dilaton effective action approach and show that they compute identical quantities. As a result of this…
