Query: GUP corrections to Dirac oscillator in the external magnetic field   We have studied (2+1) dimensional Dirac oscillator (DO) in an external
magnetic field in the framework of generalized uncertainty principle (GUP). We
have calculated the perturbative corrections for first few energy levels. We
show that the infinite degeneracy of lowest Landau level is partially lifted
due to GUP correction and obtained a critical value of the magnetic field for
which there is no GUP correction and the DO stops oscillating.
