dc.description.abstractenWe consider a quantum lattice system with infinite-dimensional on-site Hilbert space, very similar to the Bose–Hubbard model. We investigate many-body localization in this model, induced by thermal fluctuations rather than disorder in the Hamiltonian. We provide evidence that the Green–Kubo conductivity κ(β), defined as the time-integrated current autocorrelation function, decays faster than any polynomial in the inverse temperature β as β→0 . More precisely, we define approximations κτ(β) to κ(β) by integrating the current-current autocorrelation function up to a large but finite time τ and we rigorously show that β−nκβ−m(β) vanishes as β→0 , for any n,m∈N such that m−n is sufficiently large.en
