Abstract The method of few-body physics is applied to treat a D- center quantum dot system in a magnetic field. The magnetic field is applied in the z direction. Using this method, we investigate the energy spectra of low-lying states of D- center quantum dots as a function of magnetic field. The dependence of the binding energies of the ground-state of the D- center are calculated as a function of the dot radius with a few values of the magnetic field strength and compared with other results.

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.
