Abstract The q-coherent states are indeed minimum uncertainty states for corresponding q-deformed operators, The time evolution of q-coherent states are given by introducing the q-boson Hamiltoninn analogous to the one for normal bosons. It is shown that initially prepared q-coherent states are no longer the eigenstates of q-annihilation operator during time evolution and eventually become squeezing states. The squeezing properties are studied numerically.

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.
