small gaps below and above the Fermi level of about eV and eV, respectively. The SOC also results in
a pair of Dirac points along the Γ –A direction, located at ∼ eV above the Fermi level. The analysis of the
dHvA quantum oscillations supports the calculations by revealing a nontrivial Berry phase originating from the
hole and electron pockets related to the bands forming the Dirac cones. Thus, our study provides an excellent
avenue for investigating the interplay between superconductivity and nontrivial topological states.

The Majorana zero mode, which has been con- perconductivity. Among them, is most
