چکیده
The fractal velocity pattern in symmetric kink-antikink collisions ${\ensuremath{\phi}}^{4}$ theory is shown to emerge from a dynamical model with two effective moduli: the separation and internal shape mode amplitude. usefully approximates Lorentz contractions of kink antikink, previously problematic null vector amplitude at zero regularized.

Kink - Antikink Interactions in the Double Sine - Gordon Equation
As 71 is varied over the range ~ < ~/< ~c, this potential exhibits a variety of structures. Although in later sections we shall discuss these different structures in some detail [2], it is important here to provide a qualitative feeling for them. Clearly, for ~ _+ oo, 'V(~) reduces to a sine-Gordon [SG] form for q~, while for 71 = 0, it leads to a SG form for q~/2. Thus in both these limits the...

The symmetric dynamics of two kinks and one antikink in classical (1+1)dimensional φ theory is investigated. Gradient flow is used to construct a collective coordinate model of the system. The relationship between the discrete vibrational mode of a single kink, and the process of kink-antikink pair production is explored. ∗ e-mail address: [email protected] † e-mail address: M.Houari@d...
متن کاملObservation of locked optical kink-antikink spatial shock waves.
We report the first experimental observation of optical spatial shock-wave pairs. The shock waves consist of two coupled kink and antikink beams that remain locked to each other throughout propagation in a nonlinear diffusion-driven photorefractive crystal. These coupled shock-wave pairs move undistorted at angles that fall outside their original angular sector of propagation.
متن کاملA realistic heat bath : theory and application to kink - antikink dynamics
We propose a new method of studying a real-time canonical evolution of fieldtheoretic systems with boundary coupling to a realistic heat bath. In the free-field case the method is equivalent to an infinite extension of the system beyond the boundary, while in the interacting case the extension of the system is done in linear approximation. We use this technique to study kink-antikink dynamics i...
متن کاملKink-boundary collisions in a two-dimensional scalar field theory
In a two-dimensional toy model, motivated from five-dimensional heterotic M theory, we study the collision of scalar field kinks with boundaries. By numerical simulation of the full two-dimensional theory, we find that the kink is always inelastically reflected with a model-independent fraction of its kinetic energy converted into radiation. We show that the reflection can be analytically under...
