Influence of anharmonic convex interparticle potential and Shapiro steps in the opposite direction of driving force
Sonja Gombar, Petar Mali, Slobodan Radosevic +3
The response function and largest Lyapunov exponent analysis were applied to the driven overdamped Frenkel-Kontorova model with two types of anharmonic convex interparticle potenti…

Exciton dynamics in different aromatic hydrocarbon systems
Milica Rutonjski, Petar Mali, Slobodan Radosevic +3
The exciton dispersion is examined in the case of four selected prototypical molecular solids: pentacene,tetracene,picene,chrysene. The model parameters are determined by fitting t…

Complexity of Shapiro steps
Petar Mali, Andjela Sakota, Jasmina Tekic +3
We demonstrate on the example of the dc+ac driven overdamped Frenkel-Kontorova model that an easily calculable measure of complexity can be used for the examination of Shapiro step…
