Vortex-core Majorana coupling to a chiral edge in a $p_x+i{p}_y$ superconductor: Nonmonotonic spectral reorganization and coherent fermion-parity dynamics

Peiyao Liu, Yi Zhou

We study how vortex--edge coupling reorganizes the low-energy sector of a finite two-dimensional \(p_x+ip_y\) superconducting disk as a function of the vortex--boundary separation…
