Abstract

In recent years, the ⌽4 field theory became of interest as a one-dimensional model for structural phase transitions. In particular, it was shown that in a linear chain of harmonically coupled particles, which in addition sit in local double minimum potentials, ordered clusters exist. The walls separating ordered clusters are the kinks of ⌽4-theory [1]. The possible relevance of an ensemble of independently moving kinks to the spectrum of scattered neutrons and light has been investigated [1,2].
