Chemical potential and magnetization oscillations in two-dimensional QED at finite temperature and density

Based on our previous work the de Haas–van Alphen effect in two-dimensional QED at finite temperature and density is investigated. It is shown that this effect is demonstrated not only through magnetization oscillations, but also through chemical potential oscillations. Contrary to earlier work [And...

Description
Summary:Based on our previous work the de Haas–van Alphen effect in two-dimensional QED at finite temperature and density is investigated. It is shown that this effect is demonstrated not only through magnetization oscillations, but also through chemical potential oscillations. Contrary to earlier work [Andersen and Haugset, Phys. Rev. D 51 (1995) 3073], the magnetization oscillation we studied has a correct non-relativistic limit at zero temperature and low particle densities.
