- Abstract summary: We study the propagation of electrons in a circular quantum dot of gapped graphene subject to the magnetic flux $phi$.
We identify different scattering regimes as a function of the physical parameters such as the incident electronic energy, potential barrier, radius of quantum dot, gap and $phi$.

- Abstract: We study the propagation of electrons in a circular quantum dot of gapped
graphene subject to the magnetic flux $\phi$. We present analytical expressions
for the eigenstates, scattering coefficients, scattering efficiency and radial
component of the reflected current. We identify different scattering regimes as
a function of the physical parameters such as the incident electronic energy,
potential barrier, radius of quantum dot, gap and $\phi$. We choose two values
of the flux $\phi=1/2, 3/2$ and show that for low energy of the incident
electron, the scattering resonances appear and the far-field scattered current
presents distinct preferred scattering directions.

Our analysis reveals that photon dissipation has a strikingly asymmetric behavior in the two configurations with a much more dramatic role on the holon entanglement propagation than for the doublon case.
