Abstract
Using the spin Hamiltonian method, we have studied the dynamic instability of quasi-one-dimensional spin chains, which are models of the corresponding conjugated polymers. We have considered the example of chain deformation leading to a singular response of the original one-dimensional problem. We have formulated the conditions for activationless character of excitations having multiplicity of the ground state.
