演題：Proposal for experimental realization of quantum spin chains with quasiperiodic interaction using Rydberg atoms
要旨：
Investigating the localization properties of interacting disordered systems plays a crucial role in understanding the fundamental origins of both the emergence and the breakdown of statistical mechanics in closed quantum systems. However, simulating such systems on classical computers is challenging due to their complexity. On the other hand, recent advances in experimental technology have made it possible to realize closed quantum systems with high controllability. In particular, Rydberg atoms [1] are an emerging platform for quantum simulation, as they offer the advantage of individual control over the spatial positions of atoms and the ability to tune their interactions.
In this talk, I will talk about my recent work proposing an experimental method to realize S=1/2 and S=1 quantum spin models with quasiperiodic interactions using Rydberg atoms [2]. I will also present numerical results for these models, confirming that they exhibit a many-body critical (MBC) regime [3], a newly reported localization phenomenon distinct from both ergodic and many-body localized phases.
