Abstract: | We present a model with a strong fermion self-interaction and an induced gravitational interaction in five-dimensional space-time.
In the strong-coupling regime, this model develops a spontaneous breaking of translational invariance, which results in localizing
light particles on the (3+1)-dimensional domain wall embedded in the anti-de Sitter five-dimensional space-time. We obtain the corresponding low-energy
effective action and investigate kink-type vacuum solutions in a quasiflat Riemannian metric. We discuss the physics of light
particles in 3+1 dimensions and establish the fundamental relations between the induced gravitational constant and both the curvature in the
five-dimensional anti-de Sitter space-time and the Newton gravitational constant of our universe.
Dedicated to Yu. V. Novozhilov on his 80th birthday
