- Abstract: We explore the topology-disorder phase diagram by simulating one-dimensional
Su-Schrieffer-Heeger (SSH) model with quasiperiodic disorder using a
programmable superconducting simulator. We experimentally map out and identify
various trivial and topological phases with extended and localized bulk states.
We find that in the topological phase the bulk states can be critically
localized without mobility edge or contain both critically and completely
localized states. In addition, there exist trivial and topological intermediate
phases with mobility edge and coexistence of extended and completely localized
states. The presence of the surprisingly rich phases in the simple SSH model
with quasiperiodic disorder sheds new light on the investigation of the
topological and localization phenomena in condensed-matter physics.

We show how photon-mediated interactions give rise to a plaquette-ordered bond pattern in the atomic ground state.
The pattern opens a non-trivial topological gap in 2D, resulting in a higher-order topological phase hosting corner states.
Our work shows how atomic quantum simulators can be harnessed to investigate novel strongly-correlated topological phenomena.

We find that the complexity of quantum many-body states, defined as a spread, may serve as a new probe that distinguishes topological phases of matter.
We illustrate this analytically in one of the representative examples, the Su-Schrieffer-Heeger model, finding that spread complexity becomes constant in the topological phase.

We perform a detailed analysis of the phase diagram at half- and incommensurate fillings, in the mean-field approximation.

We conjecture that no direct transition between distinct MBL orders can occur; rather, a thermal phase always intervenes.
Motivated by recent advances in Rydberg-atom-based quantum simulation, we propose an experimental protocol where the intervening thermal phase can be diagnosed via the dynamics of local observables.
