Cover Story: Variation in the transcriptional activity of DNA fibres has been hypothesized to promote their self-organization in the cell's nucleus. We model the activity as stronger-than-thermal fluctuations and study the non-equilibrium phase separation of active–passive polymer mixtures. Examining the non-equilibrium steady states reveals analogies with equilibrium phase-separated polymer mixtures. We point out interesting observations that indicate general principles behind the non-equilibrium phase transition. View this paper

It is well known that the statistical mechanical theory of liquids has been lagging far behind the theory of either gases or solids, See for examples: Ben-Naim (2006), Fisher (1964), Guggenheim (1952) Hansen and McDonald (1976), Hill (1956), Temperle...
