RESEARCH ANNOUNCEMENTS——Coupled Diffusion Processes

Coupled diffusion processes (or CDP for short) model the systems of molecular motors, which attract much interest from physicists and biologists in recent years. The pro-tein moves along a filament called the track, and it is crucial that there are several inner states of the protein and the u‘nderlying chemical reaction causes transitions among different inner states, while chemical energy can be converted to mechanical energy by rachet effects. In this sense, the protein becomes a motor and is called a Brownian particle coupled with a chemical reaction. The impact of the chemical reaction can be considered as a particle source, hencethe Fokker-Planck equation should be
