      abstract     = {The Josephson diode effect, where the switching current
                      magnitude depends on its direction, arises when both
                      time-reversal and inversion symmetries are broken, often
                      achieved by a combination of spin-orbit interaction and
                      applied magnetic fields. Taking advantage of the strong
                      spin-orbit coupling inherent in three-dimensional
                      topological insulators, we study this phenomenon in
                      Nb/Bi0.8⁢Sb1.2⁢Te3/Nb Josephson weak-link junctions.
                      Under an in-plane magnetic field perpendicular to the
                      current direction, we observe a pronounced Josephson diode
                      effect with efficiencies up to $7\%.$ A crucial component of
                      this behavior is the nonsinusoidal current-phase
                      relationship and an anomalous phase shift, which we
                      attribute to the presence of a ballistic supercurrent
                      component due to the surface states. These findings open up
                      new avenues for harnessing and controlling the Josephson
                      diode effect in topological material systems.},
