Description
Recent discoveries of pressure-influenced superconducting critical temperature(Tc) in semi-metallic transition metal dichalcogenides(WTe2, MoTe2) have intrigued deep research on TMDs. Both the semi-metallic TMDs have been found to host the Weyl semi-metal phase with tilted Weyl nodes. Using a semiclassical picture to bypass the hurdle of bulk-surface inseparability, we derive the superconductor vortex spectrum in non-magnetic Weyl semimetals with tilted Weyl nodes and show that it stems from the Berry phase of orbits in the continuum limit. We have found that upon tilting the vortex, the existence of zero modes depends on the vortex tilt: if the vortex tilts beyond that of the Weyl nodes, there is no Majorana zero mode.
