We optimise stationary structures, as well as barrier breakdown points for a critical tilting force were depinning of the chain happens. These special points can be obtained straight for- wardly by the tool of Newton trajectories. We explain the theory and add examples for a finite-length chain of a fixed number of 2, 3, 4, 5 and 23 particles.18 p.application/pdfeng(c) Taylor and Francis, 2019Química físicaEstructura electrònicaTeories no linealsPhysical and theoretical chemistryElectronic structureNonlinear theoriesinfo:eu-repo/semantics/article6856742020-03-18info:eu-repo/semantics/openAccess
