- Abstract: The fate of many-body localization in long-range interacting systems is not
fully settled. For instance, the phase boundary between ergodic and many-body
localized regimes is still under debate. Here, we use Floquet dynamics which
can induce many-body localization in a clean long-range interacting system
through spatiotemporal disorder, which are realized by regular operation of
random local rotations. The phase diagram has been determined for two types of
uniform and nonuniform long-range couplings. Our Floquet mechanism shows more
localizing power than conventional static disorder methods as it pushes the
phase boundary in favor of the localized phase. Moreover, our comprehensive
long-time simulations provide strong support for obtained results based on
static analysis.

Analysing the convergence of these continued fractions, localisation or its absence can be determined, yielding in turn the critical points and mobility edges.
Results are exemplified by analysing the theory for three quasiperiodic models covering a range of behaviour.
