Description
Current-Induced Rotation and Modelling of Molecular-Scale Gears

The possibility of creating nanoscale molecular gears able to transfer motion has opened novel routes to implement true molecule-based mechanical analogs[1].
In the first part, we investigate, within model Hamiltonian approach, the rotational dynamics of a molecular gear. For this, we combine Langevin dynamics and non-equilibrium Green’s functions
to computed a current-induced torque, which allows to study the influence of the electronic system on the rotational dynamics. Our model
provides the rotational analog of the Anderson-Holstein Hamiltonian.

In the second part, we focus on rotation transfer among many gears. In particular, we use molecular dynamics (MD) simulation and also analytic approach to investigate the dynamics of coupled gears
for two gears and many gears problem; Then we demonstrate the solution analytically and numerically.
