| Popis: | We explore the two-dimensional motion of relativistic electrons when they are trapped in magnetic fields having spatial power-law variation. Its impacts include lifting of degeneracy that emerged in the case of the constant magnetic field, special alignment of Landau levels of spin-up and spin-down electrons depending on whether the magnetic field is increasing or decreasing from the centre, splitting of Landau levels of electrons with zero angular momentum from that of positive one and the change in the equation of state of matter. Landau quantization (LQ) in variable magnetic fields has interdisciplinary applications in a variety of disciplines ranging from condensed matter to quantum information. As examples, we discuss the increase in quantum speed of the electron in presence of spatially increasing magnetic field; and the attainment of super Chandrasekhar mass of white dwarfs by taking into account LQ and Lorentz force simultaneously. Comment: 12 pages including 6 figures; based on the talk given in the parallel session "Strong Electromagnetic and Gravitational Field Physics: From Laboratories to Early Universe" in the Sixteenth Marcel Grossmann Meeting held online during July 5-10, 2021; to appear in the proceedings of Sixteenth Marcel Grossmann Meeting |
