An effective field analysis of magnetic orbit-to-orbit interactions in a two-dimensional electron gas
An effective field Schrödinger equation accounting for the effect of the magnetic orbit-to-orbit interaction between electrons in a two-dimensional electron gas (2DEG) is considered. This is formulated out from the effective single-particle equation using the Hartree approximation. As a specific example, a 2DEG in a Hall bar with rectangular geometry is considered, where such equation is reduced to a one-dimensional Schrödinger equation. The effect of constant and inverse position-dependent magnetic orbit-to-orbit interaction potentials to the energy levels of the 2DEG is calculated perturbatively.
