Variational Approach to Excited Fermions on Kinks
Herbert Weigel, Danial Saadatmand
We study the back-reaction of fermion fields on the kink solution in one space and one time dimension. We employ a variational procedure to determine an upper limit for the minimum…

Phonons scattering off discrete asymmetric solitons in the absence of a Peierls-Nabarro potential
Danial Saadatmand, Aliakbar Moradi Marjaneh, Alidad Askari +1
We analyze the interaction of lattice vibrations (phonon wave-packets) with an asymmetric kink soliton initially at rest. We employ the model in one space and one time dimens…
