Entanglement measures for nonconformal D-branes

We study various entanglement measures associated with certain nonconformal field theories. We consider nonconformal D p -brane backgrounds, which are dual to these field theories, for our holographic analysis. Restricting our interests in p =1 , 2, 4, we explicitly compute properties of holographic entanglement entropy and the entanglement wedge cross section, E_W, corresponding to two parallel strip shaped boundary subregions in these setups. We study low and high temperature behaviors of these quantities analytically as well as by using numerical methods. In all cases, the E_W decreases monotonically with temperature. We observe discontinuous jumps in E_W, while the width of (as well as the separation between) the subregions reaches critical values in all the cases considered. However, the corresponding holographic mutual information I_M continuously decreases to zero for the aforementioned configurations. We also notice that the conjectured inequality E_W≥I_M/2 still holds for nonconformal field theories as well. We analytically determine the critical separation between these subregions that triggers a phase transition in the holographic mutual information.
