Macroscopic quantum states can be easily created and manipulated within semiconductor microcavity chips using exciton-photon quasiparticles called polaritons. Besides being a new platform for ...

(Nanowerk News) The ratchet mechanism is a fascinating energy-conversion system that converts disorderly or random motion into orderly, directed movement through a process known as spontaneous ...

The proposed ratchet mechanism utilizes the asymmetry in surface wettability between the smooth and rough faces of the teeth of a geometrically symmetric gear to achieve ratcheting motion. The ratchet ...
