description

This Chapter does not follow the main line of the book that is the theory of HF compounds but illustrates how the ideas of FC may be applicable to describe a very dissimilar system. Namely, here we consider a novel mechanism for explaining the matter-antimatter asymmetry of the universe. We assume that the universe starts from completely symmetric state and then, as it cools down, it undergoes a quantum phase transition, which in turn causes an asymmetry between matter and anti-matter. As we shall see the quantum phase transition is represented by FCQPT. The mechanism does not require the baryon number violating interactions or \({\textit{CP}}\) violation at a microscopic level. The state FC emerging behind FCQPT can be viewed as the state possessing the supersymmetry that interchanges bosons and fermions eliminating the difference between them. Thus restoring one important symmetry, the FC state violates another essential symmetry destroying matter—anti-matter symmetry. Our analysis of the matter antimatter asymmetry is in the context of remarkable experimental results obtained in the condensed matter physics.
