Kink solutions in logarithmic scalar field theory: Excitation spectra, scattering, and decay of bions

Ekaterina Belendryasova, Vakhid A. Gani, Konstantin G. Zloshchastiev

We consider the (1+1)-dimensional Lorentz-symmetric field-theoretic model with logarithmic potential having a Mexican-hat form with two local minima similar to that of the quartic…
