Interactions generically have important eﬀects on the topological quantum phases. For a quantum anomalous Hall (QAH) insulator, the presence of interactions can qualitatively change the topological phase diagram which, however, is typically hard to measure in the experiment. Here we propose a novel scheme based on quench dynamics to detect the mean-ﬁeld topological phase diagram of an interacting Chern insulator, with nontrivial dynamical quantum physics being uncovered. We focus on a two…

### Quantum Phases of Three-Dimensional Chiral Topological Insulators on a Spin Quantum Simulator.

- PhysicsPhysical review letters

This work investigates the three-dimensional topological insulators in the AIII (chiral unitary) symmetry class, which yet lack experimental realization, and experimentally demonstrates their topological properties, where a dynamical quenching approach is adopted and the dynamical bulk-boundary correspondence in the momentum space is observed.

### Observing Topological Charges and Dynamical Bulk-Surface Correspondence with Ultracold Atoms.

- PhysicsPhysical review letters

It is observed that the total charges in the region enclosed by BISs define a dynamical topological invariant, which equals the Chern number of the postquench band and also characterizes the topological pattern of a dynamicals field emerging on the BISS, rendering the dynamical bulk-surface correspondence.

### Topological Invariants for Quantum Quench Dynamics from Unitary Evolution.

- Physics, MathematicsPhysical review letters

The concept of loop unitary constructed from the unitary time-evolution operator is introduced and its homotopy invariant fully characterizes the dynamical topology, proving that the invariant is precisely equal to the change in the Chern number across the quench, regardless of the initial state.

This work investigates the quench dynamics of a spin-orbit-coupled two-dimensional Fermi gas in which the Zeeman field serves as the major quench parameter and identifies three post-quench dynamical phases according to the asymptotic behaviour of the order parameter.
