Edge states, Majorana fermions, and topological order in superconducting wires with generalized boundary conditions

We study the properties of one-dimensional topological superconductors under influence generic boundary conditions mimicking coupling with external environments. identify a general four-parameter classification effects and show that particle-hole reflection symmetries can be broken or preserved by appropriately fixing parameters. When symmetry is broken, protection edge modes lost due to hybridization degrees freedom. assess robustness in various regimes considering different quantifiers properties. In particular, we investigate resilience long-distance, edge-to-edge quantum mutual information squashed entanglement, measuring nonlocal correlations Majorana excitations. Besides their relevance for open dynamics systems, these results may provide useful guide appropriate embedding low-dimensional systems on nanodevices realistic conditions.
