High-speed kinks in a generalized discrete phi4 model.
We consider a generalized discrete phi4 model and demonstrate that it can support exact moving kink solutions in the form of tanh with an arbitrarily large velocity. The constructed exact moving solutions are dependent on the specific value of the propagation velocity. We demonstrate that in this class of models, given a specific velocity, the problem of finding the exact moving solution is int...
متن کاملTravelling kinks in discrete φ 4 models
In recent years, three exceptional discretizations of the φ 4 model have been discovered [S97, BT97, K03] which support translationally invariant kinks, i.e., families of stationary kinks centered at arbitrary points between the lattice sites. We address the question of the persistence of these kinks for nonzero velocity. By computing the Stokes constants in beyond-all-order asymptotic expansio...

In recent years, three exceptional discretizations of the φ 4 theory have been discovered [SW94, BT97, K03] which support translationally invariant kinks, i.e. families of stationary kinks centred at arbitrary points between the lattice sites. It has been suggested that the translationally invariant stationary kinks may persist as sliding kinks, i.e. discrete kinks travelling at nonzero velocit...

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...
