Kink excitation spectra in the (1+1)-dimensional ${\phi }^8$ model

Vakhid A. Gani, Vadim Lensky, Mariya A. Lizunova

We study excitation spectra of BPS-saturated topological solutions -- the kinks -- of the ${\phi }^8$ scalar field model in $(1+1)$ dimensions, for three different choices of the model p…
