"Entanglement in the XXZ Chain with a Gradient"

We study the XXZ spin chain in the presence of a slowly varying magnetic
field gradient. First, it is shown that a local density approximation 
perfectly
captures the ground-state magnetization profile. Furthermore, we demonstrate
how the recently introduced technique of curved-spacetime CFT yields
a very good approximation of the entanglement profile. Finally, the front
dynamics is also studied after the gradient field has been switched off.
