As a possible remedy we suggest to consider nontrivial boundary conditions on x-y plane by in-equivalently quantizing the exciton in background magnetic field. This inequivalent quantization is based on von Neumann's method of self-adjoint extension, which is characterized by a parameter Σ. We obtain bound state solution and scattering state solution, which in general depend upon the self-adjoint extension parameter Σ. The parameter Σcan be used to fine tune the optical absorption coefficient K(Σ) to match with the experiment.5 pages, 1 figureQuantum PhysicsHigh Energy Physics - TheoryMathematical Physicstext
