WebIn these lecture notes, we introduce the description of kinks in φ4-theory and the various physical processes that govern their dynamics. The notes are aimed at advanced undergraduate students, and emphasis is placed on stimulating qualitative insight into the rich phenomenology encountered in kink dynamics. WebAn account is given of the main steps that led the research group in Rome, to which the author belongs, to the formulation of the charge-density-wave scenario for high- T c superconducting cuprates. The early finding of the generic tendency of strongly correlated electron systems with short range interactions to undergo electron phase separation was …

Web25 mei 2024 · The kinks in theory have large spatial extent, as well as not being symmetric in x. Thus there is no obvious definition for the centre of a kink and we must make a somewhat arbitrary choice. In this work we define the center of the kink as the point that crosses the maximum of the potential energy. WebSpectrum of the obtained kinks coincides with that of Dirac-Born-Infeld type effective theory. We study tachyon kinks with and without electromagnetic fields in the context of … nus callsignThe 1-soliton solution for which we have chosen the positive root for is called a kink and represents a twist in the variable which takes the system from one solution to an adjacent with . The states are known as vacuum states, as they are constant solutions of zero energy.
