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…
Excited fermions on kinks and the Dirac sea
Danial Saadatmand, Herbert Weigel
We study quantum effects of recently discovered kink solitons which are constructed self-consistently by coupling to a single, excited fermion bound state. Our studies are based on…
Quantum Effects of Solitons in the Self-Dual Impurity Model
I. Takyi, H. Weigel
We compute the vacuum polarization energies (VPE) of solitons in a self-dual impurity model in which the soliton profiles take the shape of a separated kink-antikink pair. Classica…
Quantum energies of BPS vortices in and
N. Graham, H. Weigel
We consider vortices in scalar electrodynamics and compute the leading quantum correction to their energies for the BPS case of identical classical masses of the Higgs and gauge fi…
Quantum Corrections to Soliton Energies
N. Graham, H. Weigel
We review recent progress in the computation of leading quantum corrections to the energies of classical solitons with topological structure, including multi-soliton models in one…
Winding number dependence of quantum vortex energies at one-loop
N. Graham, H. Weigel
We compute the one-loop vacuum polarization energies of Abrikosov-Nielsen-Olesen (ANO) vortices with topological charge in scalar electrodynamics, for the BPS case of equal gau…
