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…

Tomographic imaging of superconducting order using particle-hole interference
Archisman Panigrahi, Vladislav Poliakov, Leonid Levitov
Superconducting phases with exotic symmetries that differ from the underlying crystalline lattice are at the focus of superconductivity research. Yet, despite intense interest, det…
