摘要：
We study the energy levels of fermions magnetically confined in graphene through an electrostatic potential and an inhomogeneous gap, including 42 inside and 41 outside of the generated quantum dots. Our findings illustrate that the energy levels exhibit either symmetric or asymmetric behavior, contingent upon the signs of z and the quantum angular momentum number m. It is discovered that 41 acts by breaking the symmetry and generating a new set of energies.
