# On the kinks and dynamical phase transitions of α-helix protein chains

@article{Rosu1996OnTK, title={On the kinks and dynamical phase transitions of $\alpha$-helix protein chains}, author={Haret C. Rosu}, journal={Il Nuovo Cimento D}, year={1996}, volume={18}, pages={477-481} }

SummaryHeuristic insights into a physical picture of Davydov’s solitonic model of the one-dimensional protein chain are presented supporting the idea of a non-equilibrium competition between the Davydov phase and a complementary, dynamical-«ferroelectric» phase along the chain.
