abstract
The aim of the paper is to show the probabilistically strong well-posedness of rough differential equations with distributional drifts driven by the Gaussian rough path lift of fractional Brownian motion with Hurst parameter $H\in(1/3,1/2)$. We assume that the noise is nondegenerate and the drift lies in the Besov-H\"older space $\mathcal{C}^\alpha$ for some $\alpha>1-1/(2H)$. The latter condition matches the one of the additive noise case, thereby providing a multiplicative analogue of Catellier-Gubinelli in the regime $H\in(1/3,1/2)$.

Construction of the 1d Self-repelling Brownian Polymer
The 1d self-repelling Brownian polymer, with the singular Dirac interaction, is constructed in the annealed random-environment setting as a unique energy solution, and it is shown to be superdiffusive.

On the density of singular SDEs with fractional noise and applications to McKean-Vlasov equations
Singular fBm-driven SDEs with distributional drifts have densities with Besov regularity and Gaussian tails, and the associated McKean-Vlasov equations are well-posed down to the subcritical scaling threshold.
