Anisotropic Josephson couplings in triplet superconductor networks produce frustrated d-vector textures that trap nonintegral flux, including pi-flux above a critical antisymmetric coupling strength.
In a monitored Rashba chain the disconnected entanglement entropy stays topological for a time linear in system size because monitoring switches between degenerate topological states while poisoning other quasiparticles.
Numerical study demonstrates controlled transport of Z4 parafermion edge states in a ladder model and quantifies the adiabatic speed limit under realistic conditions.
A microscopic model of an SSH-superconductor junction finds stable quasiparticle states inside the gap for bulk superconductors but finite temperature-dependent lifetimes from phase fluctuations in lower-dimensional superconductors.
Edge reconstruction of a ν=1 quantum Hall edge into a ν=1/3 side strip doubles topological sectors to Z2×Z2 degeneracy, producing 4π Josephson periodicity with energetically decoupled Z2 states.
