Abstract A two-state model is presented for polarization relaxation in condensed matter. The dynamics of relaxation is treated with quantum transition theory. The physical meaning of the so-called time-dependent transition rate is clarified. The new model not only gives the fractional exponential and power-law relaxation functions naturally, but also indicates that the universality of the relaxation law results from the scaling behavior of low-frequency effective spectrum.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
