    "abstract": "We investigate the presence of topological twistons in crystalline\npolyethylene. We describe crystalline polyethylene with a model that couples\nthe torsional and longitudinal degrees of freedom of the polymeric chain by\nmeans of a system of two real scalar fields. This model supports topological\ntwistons, which are described by exact and stable topological solutions that\nappear when the interaction between torsional and longitudinal fields is\npolynomial, containing up to the sixth power in the fields. We calculate the\nenergy of the topological twiston, and the result is in very good agreement\nwith the value obtained via molecular simulation.",
