We propose a simple phenomenological model for describing the conformational dynamics of biopolymers via the nonlinearity-induced buckling and collapse (i.e. coiling up) instabilities. We describe the buckling instability analytically, and then demonstrate the role of both instabilities in the folding of biopolymers through the numerical simulations of the(More)

A discrete nonlinear Schrödinger (NLS) model with long-range dispersive interactions describing the dynamical structure of DNA is proposed. Dispersive interactions of two types: the power dependence r −s and the exponential dependence e −β r on the distance, r, are studied. For s less than some critical value, scr, and similarly for β ≤ βcr there is an(More)
