We study the presence of kinks in models described by two real scalar fields in bidimensional spacetime. We generate new two-field models, constructed from distinct but important one-field models, and we solve them with techniques that we introduce in the current work. We illustrate the results with several examples of current interest to high energy physics.

The One

We investigate several models described by real scalar fields, searching for topological defects, and investigating their linear stability. We also find bosonic zero modes and examine the thermal corrections at the one-loop level. The classical investigations are of direct interest to high energy physics and to applications in condensed matter, in particular to spatially extended systems where fronts and interfaces separating different phase states may appear. The thermal investigations show that the finite temperature corrections that appear in a specific model induce a second-order phase transition in the system, although the thermal effects do not suffice to fully restore the symmetry at high temperature.

Quintessence tracking models have been put forward as a way of providing the missing cosmic energy required to make up for the shortfall between the observed clumped matter density and the critical density - as seems to be demanded by current observations - as well as simultaneously solving the initial condition problem faced by a cosmological constant. The robustness of this tracking quintessence scenario has recently been studied in more general cosmologies inspired by high-energy physics - cosmologies that include multiple scalar fields, brane corrections to the Hubble expansion law as well as potentials that decay with expansion. Here we give a summary of these results and apply them to the concrete case of a model with two scalar fields.
