Mechanical laws of the Rindler horizon

Understand

Gravitational perturbations of flat Minkowski space make the Rindler horizon dynamical: the horizon satisfies mechanical laws analogous to the ones followed by black holes.

• We describe the gravitational perturbation of Minkowski space using perturbative field-theoretical methods.
• The change in the area of the Rindler horizon is described in terms of the deflection of light rays by the gravitational field.
• The difference between the area of the perturbed and the unperturbed horizon is related to the energy of matter crossing the horizon.
