In the non-Hermitian Kitaev chain, preserved particle-hole symmetry makes the open-chain topological transition coincide with the periodic one and forces zero-energy Majorana modes to appear as reciprocal localization pairs that cancel the non-Hermitian skin effect.
Rydberg atoms on a triangular lattice host a deconfined quantum critical point between 1/3 and 2/3 filling phases, with predicted critical exponents, emergent U(1) symmetry in a CFT, and numerical confirmation.
Derivative of Krylov spread complexity diverges logarithmically at SSH topological transitions and is bounded by fidelity susceptibility in general two-band Hamiltonians, with a non-unitary duality between phases.
Numerical tests on bosonic Laughlin and Moore-Read states show that modular Hamiltonian methods recover expected topological quantities only when system sizes are large enough relative to the correlation length.
