The Yang-Baxter method is a powerful tool for studying integrable systems, but proving whether a system possesses local conserved quantities remains challenging. Shiraishi’s proof of the XYZ model’s nonintegrability with a magnetic field inspired the authors’ demonstration of the PXP model’s nonintegrability, previously only conjectured via level statistics. As the PXP model is a key example of quantum many-body scars exhibiting exotic long-time behavior, the present work highlights that such behavior is unrelated to local conserved quantities and introduces a graph-theoretical approach, suggesting universality in nonintegrability proofs.

The authors demonstrate here that multigap topological phases hosting an Euler invariant relate to quantum-geometric bounds. These bounds constrain optical weights and sizes of adjacent gaps. The results are validated upon recasting them as optical absorption rates and open up a route to determine experimentally the topological Euler class through momentum- and frequency-resolved measurements. Moreover, it is shown that a singular quantum geometry of topological Euler band nodes induces observable features, such as quantized optical conductivities.
