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…
Dynamics of Frenkel excitons in pentacene
Sonja Gombar, Petar Mali, Milan Pantić +2
The dispersion relation for noninteracting excitons and the influence of perturbative correction is examined in the case of pentacene structure. The values of exchange integrals ar…
Correlation between quantum entanglement and quantum coherence in the case of XY spin chains with the Dzyaloshinskii-Moriya interaction
Sonja Gombar, Petar Mali, Milan Pantic +2
Recently, there has been an increased interest in studying quantum entanglement and quantum coherence. Since both of these properties are attributed to the existence of quantum sup…
