The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Analysis of entanglement-spectrum degeneracies and adiabatic connections identifies multiple symmetry-protected topological (SPT) phases. These phases could be realized in arrays of vortex-bound Majorana modes on the surface of a topological superconductor.

C2weakest assumption

That the DMRG and variational uniform matrix product state simulations on the four-leg ladder accurately capture the true ground states and that entanglement spectrum degeneracies reliably diagnose SPT order without significant finite-size or truncation artifacts.

C3one line summary

Numerical simulations of the triangular Majorana-Hubbard ladder reveal multiple symmetry-protected topological phases identified through entanglement spectrum degeneracies and adiabatic connections.
