We study theoretically a bistable system with time-delayed feedback driven by a weak periodic force. The effective potential function and the steady-state probability density are derived. The delay time and the strength of its feedback can change the shapes of the potential wells. In the...

The biological systems described as soft matter on mesoscopic scales manifest, in contrast to hard (condensed) matter, a number of characteristics: complexity, flexibility, and fluctuations. Due to these, there arise a variety of conformational and nonequilibrium phase transitions at...
