• Influence of quadrupole–quadrupole-type interaction on the chaotic dynamics of $\alpha$-helical proteins

By proposing a model Hamiltonian in the first quantised form we investigate the chaotic dynamics of $\alpha$-helical proteins by taking into account the quadrupole–quadrupole-type interaction. The dynamics is studied byderiving Hamilton’s equations of motion and by plotting the time-series evolution and phase-space trajectories. Chaotic trajectories are observed in the phase-space plots. The effect of the interaction parameters on the stabilityof proteins is also discussed.

• A chaotic study on Heisenberg ferromagnetic spin chain using Dzyaloshinski–Moriya interactions

The chaotic dynamics of a one-dimensional Heisenberg ferromagnetic spin chain incorporating Dzyaloshinski–Moriya (D–M) interaction, dipole–dipole and quadrupole–quadrupole interactions has been investigated. The studies are carried out by plotting phase diagrams and chaotic trajectories. We then analyse the stability of the system using the Lyapunov stability analysis.
