Speaker: Ruixing Zhang (University of Tennessee Knoxville) Title: Microscopic Fingerprint of Chiral Superconductivity Abstract: Chiral superconductors are predicted to break time-reversal symmetry and host topological excitations such as Majorana modes, yet direct evidence of chiral pairing has remained elusive. In this talk, I will present real-space evidence of intrinsic chiral superconductivity in a single atomic layer of tin on Si(111). Using high-resolution quasiparticle interference imaging, we identify symmetry-locked nodal and antinodal points in the Bogoliubov quasiparticle wavefunction, tightly bound to atomic defects in the tin lattice. These nodal features, together with their surrounding texture, form a microscopic fingerprint unique to chiral d-wave pairing. I will further prove, through analytic theory, that such nodal behavior of impurity states arises universally from the interplay between pairing chirality and crystalline rotational symmetry in generic two-dimensional chiral superconductors.
