Summary
A new spin-resolved transport protocol links measurable local and nonlocal conductance to the spin polarisation of Majorana corner states in 2D second-order topological superconductors.
Numerical simulations show the two corner states carry opposite spin-polarisation signs under an in-plane magnetic field, enabling unambiguous identification and labelling of each state.
The electrical signatures remain detectable even with material imperfections, addressing a key obstacle to verifying these quasiparticles in realistic devices.
Magnetic fields around 0.1 Tesla produced especially clear effects in the modelling, giving experiments a practical target for STM-based validation.
The result strengthens a route toward topological quantum computing by improving how robust, spin-defined Majorana states can be characterized and potentially controlled.
