Point-gap topology of stochastic matrices characterizes both directed transport and feedback-induced non-Markovianity in classical stochastic processes, with a topological quantum simulation of the latter.
A periodically driven dissipative SSH chain exhibits a Z x Z topological classification in its mixed steady state via ensemble geometric phases in the 0 and pi gaps.
At special drive frequencies, the leading perturbative Floquet Hamiltonian of a driven Rydberg chain maps to the XXZ model, producing emergent prethermal integrability confirmed by level statistics and entanglement in exact diagonalization.
Integrated left-right transmission asymmetry in open Floquet lattices saturates to the bulk winding number via unit population of propagating Floquet-Bloch branches.
Derives closed-form quasienergy spectra and Chern numbers for flux-switching Harper-Hofstadter models and maps topological phases via Diophantine gap labeling.
A modified SSH model supports a pair of Jackiw-Rebbi zero modes that hybridize via tunneling, enabling coherent oscillations whose period is set by the hybridization gap.
Periodic driving of the SSH model with two unitaries produces end modes whose count can mismatch the winding number, while quasiperiodic protocols yield Loschmidt echoes that oscillate near one for long times before decaying as epsilon squared, and random protocols cause rapid decay.
This is a review summarizing existing extensions of the SSH model to higher dimensions, larger unit cells, and additional terms, with case studies of their topological properties.
