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.
