Query: Kinks in higher derivative scalar field theory   We study static kink configurations in a type of two-dimensional higher
derivative scalar field theory whose Lagrangian contains second-order
derivative terms of the field. The linear fluctuation around arbitrary static
kink solutions is analyzed. We find that, the linear spectrum can be described
by a supersymmetric quantum mechanics problem, and the criteria for stable
static solutions can be given analytically. We also construct a superpotential
formalism for finding analytical static kink solutions. Using this formalism we
first reproduce some existed solutions and then offer a new solution. The
properties of our solution is studied and compared without those preexisted. We
also show the possibility in constructing twinlike model in the higher
derivative theory, and give the consistency conditions for twinlike models
corresponding to the canonical scalar field theory.
