Adiabatic motion of two-component BPS kinks

Adiabatic motion of two-component BPS kinks

The low energy dynamics of degenerated BPS domain walls arising in a generalized WessZumino model is described as geodesic motion in the space of these topological walls.

Colloidal friction: Kinks in motion.

Two–Component Dust in Spherically Symmetric Motion

Two components of spherically symmetric, inhomogeneous dust penetrating each other are introduced as a generalization of the well–known Tolman–Bondi dust solution. The field equations of this model are formulated and general properties are discussed. Special solutions with additional symmetries — an extra Killing– or homothetic vector — and their matching to the corresponding Tolman–Bondi solut...

Semi-classical mass of quantum k-component topological kinks

We use the generalized zeta function regularization method to compute the one-loop quantum correction to the masses of the TK1 and TK2 kinks in a deformation of the O(N) linear sigma model on the real line.

Gravitational kinks in two spacetime dimensions

The properties of gravitational kinks are studied within some simple models of two dimensional gravity. In spacetimes of cylindrical topology we prove the existence of kinks of constant curvature with arbitrary kink numbers. In R R spacetimes m = 1 kink solutions of the equation R = 0 are found, whereas jmj > 1 at kinks are proved not to exist. We give a detailed analysis of the behaviour of gr...
