We investigate mixed state entanglement measures of entanglement negativity and reflected entropy in bipartite states in two dimensional conformal field theories with an anomaly through appropriate replica techniques. Furthermore, we propose holographic constructions for these measures from the corresponding bulk dual geometries and find exact agreement with the field theory results. In this connection, we extend an earlier holographic proposal for the entanglement negativity to the bulk action with a gravitational Chern-Simons term and compute its contribution to the entanglement wedge cross section dual to the reflected entropy.
We investigate mixed state entanglement measures of entanglement negativity and reflected entropy for bipartite states in two dimensional conformal field theories with an anomaly through appropriate replica techniques. Furthermore we propose holographic constructions for these measures from the corresponding bulk dual geometries involving topologically massive gravity in AdS3 and find exact agreement with the field theory results. In this connection we extend an earlier holographic proposal for the entanglement negativity to the bulk action with a gravitational Chern-Simons term and compute its contribution to the entanglement wedge cross section dual to the reflected entropy.
