Description
I consider transport properties of an extended-range XX model, a candidate framework for describing dipole–dipole coupled Rydberg atom chains. With the goal of capturing the properties of the system at the intermediate time scales accessible in experiments, I discuss the possibility of approximating the system with an integrable one.
Two complementary approaches are considered. First, I develop an effective thermodynamic Bethe Ansatz (TBA) description, the associated generalized hydrodynamic (GHD) equations, and discuss their inherent limitations. Second, I construct a mean-field framework that closely parallels the TBA/GHD and appears to face similar issues. I then outline a possible route to overcoming those obstacles and highlight the striking physical properties that seem to be responsible for the difficulties in developing a complete theoretical description.
