Analytical perspectives on localized solutions of the phi-4 theory
We investigate the topological and non-topological solitons—kink and breather—in the φ4 model. Our first objective is to explain the chaotic motion of the resonantly driven kink. To this end, we consider the evolution of the kink's wobbling and rocking modes and their coupling. To improve the …

Inparticular, we obtain the masses of the lowest eigenstate as a function of the coupling strength and study the behavior of the wavefunction components. The calculation was …

The projective to Einstein correspondence and a kink on a wormhole
The first part of this thesis is concerned with $\phi^4$ field theory on a wormhole spacetime in 3 + 1 dimensions. This spacetime has two asymptotically flat ends connected by a spherical throat of radius $a$. We show that the theory possesses a kink solution which is linearly stable, and compare …

Nonperturbative renormalization in classical φ4 theory
This is an in-depth study of two analytic nonperturbative renormalization group methods used to study nonrelativistic quartic interacting systems. The model studied is that of classical real scalar φ4 theory. A variety of techniques are used including a rescaling of a nonlinear complete basis, a …
