Dr Jared Jeyaretnam ⚛️🧪 @jaredjeya.github.io · Sep 17 In particular, there have been claims of *disorder-free localization*: one finds emergent background charges which lead to an effective disorder ensemble, localising particles and leading to a claimed ultra-slow growth of entanglement. See e.g., journals.aps.org/prl/pdf/10.1... (3/7)

Inspecting this model more closely, we find that in the strong-coupling limit, spin exchange is only allowed when the forces due to dynamical particles and background charges balance out. This leads to frozen dynamics in parts of the chain, and fragmentation of the phase space! (4/7)
