Light-Cone Friedel Oscillations: a Window into van Hove Superconductivity
Archisman Panigrahi, Vladislav Poliakov, Leonid Levitov
Van Hove (vH) singularities can enhance superconductivity by generating a large pairing susceptibility. Yet, it remains challenging to experimentally establish whether pairing real…

Imaging phase winding in topological superconductors with a fork-tip Josephson STM
Vladislav Poliakov, Archisman Panigrahi
The topological phase winding in a chiral superconductor remains challenging to access by conventional real-space probes. We propose a scheme to probe this winding with a fork-tip…

Particle-Hole Ghost Interference in Superconductors
Archisman Panigrahi, Vladislav Poliakov, Leonid Levitov
Mirror-assisted optical interference can improve the fidelity of Young's double-slit interference. Here we discuss an electron analogue: particle-hole interference in superconducto…
