Solvable model of a double quantum electron layer in a magnetic field
Vladimir A. Geyler, I. Yu. Popov
Abstract
A solvable model of a double quantum electron layer in a magnetic field based on the theory of self-adjoint extensions of symmetric operators is suggested. The spectral problem reduces to a finite-dimensional one through the use of harmonic analysis on a magnetic translations group. Properties of a gap between symmetric and antisymmetric states are discussed. The model gives a linear dependence of spectral parameters on a magnetic field B.
