Abstract

In this paper, we argue that, in 2-d, the weak localisation of bosons, which occurs on the insulating side of the superconductor-insulator transition, is characterised by ρln(1/T)\rho \sim ln(1/T), as compared to σlnT\sigma \sim lnT for fermions. Such an unconventional behaviour is tied to the diffusion pole of the delocalised (uncondensed) vortices.
