Quantum gears: a simple mechanical system in the quantum regime
@article{Mackinnon2002QuantumGA, title={Quantum gears: a simple mechanical system in the quantum regime}, author={Angus Mackinnon}, journal={Nanotechnology}, year={2002}, volume={13}, pages={678-681} }
The quantum mechanics of a simple mechanical system is considered. A group of gears can serve as a model for several different systems such as an artificially constructed nanomechanical device or a group of ring molecules. An expression is derived for the quantization of the dynamics of a two-gear system. The general solution for several gears is discussed.

Since novel quantum mechanical effects, for instance, quantized heat flow, manifestation of charge discreteness, and the quantum electrodynamical Casimir effect become operative in this regime, exciting new paradigms for circuit modeling and design must be invoked in order to fully exploit the potential of this technology in sensing, computation, and signal processing applications.

The results reveal that an open radical state at the core of star-shaped pentaphenylcyclopentadiene (PPCP) favors anchoring, which helps to achieve reproducible and stepwise rotations of the single gears and transmit rotations for up to three interlocked units.
