The scaling of the correlation length of the latter was recently characterized in Probab. Duke Math. J. 172(9), 1781–1811 (2023) and arXiv:2011.08768v3, (2022); our analysis is reminiscent of the multi-scale approach of the latter work and of Combinatorica 9, 161–187 (1989) . We show that at every dyadic scale from the system size down to the lattice spacing the minimizer contains at most order-one Dirichlet energy per unit length. We also establish a quenched homogenization result in the sense that the leading order of the minimal energy becomes deterministic as the ratio system size / lattice spacing diverges. To this purpose we adapt arguments from arXiv:2401.06768, (2024) on the (d + 1)-dimensional version our the model, with a Brownian replacing the white noise potential, to obtain the initial large-scale bounds. Based on our estimate of the (p = 3)-Dirichlet energy, we give an informal justification of the geometric linearization. Our bounds, which are oblivious to the microscopic cut-off scale provided by the lattice spacing, yield tightness of the law of minimizers in the space of continuous functions as the lattice spacing is sent to zero.","lang":"eng"}],"main_file_link":[{"url":"https://doi.org/10.1007/s00440-026-01468-y","open_access":"1"}],"oa":1,"scopus_import":"1","doi":"10.1007/s00440-026-01468-y","day":"14","_id":"21379","author":[{"first_name":"Felix","full_name":"Otto, Felix","last_name":"Otto"},{"full_name":"Palmieri, Matteo","first_name":"Matteo","last_name":"Palmieri"},{"first_name":"Christian","full_name":"Wagner, Christian","id":"bf0c729b-2619-11f0-8024-9d69bb2b8b20","last_name":"Wagner"}],"article_type":"original","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"OA_type":"hybrid","language":[{"iso":"eng"}],"status":"public","quality_controlled":"1","acknowledgement":"FO and CW thank Ron Peled for insightful discussions on the white-noise multi-dimensional case in the Fall of 2023.
