        Analysis

        This paper explores the use of topological phase transitions and edge states for quantum sensing. It highlights two key advantages: the sensitivity scaling with system size is determined by the order of band touching, and the potential to generate macroscopic entanglement for enhanced metrology. The work suggests engineering higher-order band touching and leveraging degenerate edge modes to improve quantum Fisher information.

        The quantum Fisher information scales as $ \mathcal{F}_Q \sim L^{2p}$ (with L the lattice size and p the order of band touching) and $\mathcal{F}_Q \sim N^2 L^{2p}$ (with N the number of particles).

        Analysis

        This paper investigates the potential for discovering heavy, photophobic axion-like particles (ALPs) at a future 100 TeV proton-proton collider. It focuses on scenarios where the diphoton coupling is suppressed, and electroweak interactions dominate the ALP's production and decay. The study uses detector-level simulations and advanced analysis techniques to assess the discovery reach for various decay channels and production mechanisms, providing valuable insights into the potential of future high-energy colliders to probe beyond the Standard Model physics.
