Investigating localization properties of interacting disordered systems plays a crucial role in understanding thermalization and its absence in closed quantum systems. However, simulating such systems on classical computers is challenging due to their complexity. In this work, we propose a method to realize S = 1/2 and S = 1 quantum spin models with quasiperiodic interaction using Rydberg atoms by utilizing the high tunability of their spatial position. We also perform numerical calculations and show that these models host a many-body critical regime, which differs from the ergodic and many-body localization.

  1. Magnetic-field control of interactions in alkaline-earth Rydberg atoms and applications to {\it XXZ} models

    cond-mat.quant-gas 2026-04 unverdicted novelty 6.0 of 10

    Ytterbium Rydberg pairs naturally realize strongly anisotropic XXZ spin interactions that can be tuned by a magnetic field.

  2. Higgs and Nambu-Goldstone modes in a spin-1 $XY$ model with long-range interactions

    cond-mat.quant-gas 2025-12 conditional novelty 6.0 of 10

    In a 2D spin-1 XY model with 1/r^3 interactions, the Higgs mode disperses linearly and its Beliaev damping is strongly suppressed near the quantum critical point, making it observable.

  3. Programmable glassy dynamics using tunable disorder in tweezer arrays

    cond-mat.quant-gas 2025-04 conditional novelty 6.0 of 10

    The relaxation of a disordered spin system is controlled by the variance of its interaction distribution, enabling engineered glassy dynamics in one-dimensional tweezer arrays.
