Nevertheless, this task remains an open and challenging problem. Traditional centrality measures often rely on single-scale topological information, which limits their ability to fully characterize node importance. To address this issue, this paper proposes a multiscale structural contraction method based on discrete curvature for key node identification. From a geometric perspective, discrete curvature is employed to quantify the tightness of connections between nodes guiding the iterative contraction of local structures and progressively constructing a multiscale representation of the network. By integrating structural information preserved across different scales and mapping the aggregated multiscale evaluation back to the original graph, a comprehensive ranking of node importance is generated. Experimental results demonstrate that the proposed method outperforms existing baseline approaches on both real-world and synthetic networks, enabling more accurate and robust identification of structurally critical nodes.</p></div>","PeriodicalId":667,"journal":{"name":"Journal of Statistical Physics","volume":"193 7","pages":""},"PeriodicalIF":1.1,"publicationDate":"2026-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148261775","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The inherent non-Markovian nature induced by delay challenges the application of classical ergodic theory. To overcome this challenge, we introduce the concept of recurrent entrance measures, which extends the classical notion of invariant measures to non-autonomous settings. By generalizing Shcherbakov’s comparability principle to a stochastic variational framework, we prove that these measures inherit the full spectrum of recurrence properties (e.g., stationary, periodic, quasi-periodic, almost periodic, Levitan almost periodic, Bohr almost automorphic, pseudo-periodic, Birkhoff recurrent, pseudo-recurrent and Poisson stable) from the system’s coefficients, marking a shift from pathwise to statistical descriptions of recurrence. For autonomous systems, we prove uniform exponential mixing in the Wasserstein metric and further establish strong laws of large numbers and central limit theorems for solution maps. Our results provide a unified statistical framework for stochastic evolution systems with delay, with applications to physical models exhibiting memory and stochastic forcing.</p></div>","PeriodicalId":667,"journal":{"name":"Journal of Statistical Physics","volume":"193 6","pages":""},"PeriodicalIF":1.1,"publicationDate":"2026-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148281166","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such skeletons have previously been found in classes of free-fermion models. For the translation-invariant BDI and AIII free-fermion classes, it has been shown that the underlying skeleton is dense, giving an analytic approach to MPS approximation of ground states anywhere in the class. In this paper, we partially expose the skeleton in certain interacting spin chains: the <i>N</i>-state Onsager-integrable chiral clock families. We construct MPS that form a dense MPS skeleton in the gapped regions surrounding a sequence of fixed-point Hamiltonians (the generators of the Onsager algebra). Outside these gapped regions, these MPS remain eigenstates, but no longer give the many-body ground state. Rather, they are ground states in particular sectors of the spectrum. Our methods also allow us to find further MPS eigenstates; these correspond to low-lying excited states within the aforementioned gapped regions. This set of MPS excited states goes beyond the previous analysis of ground states on the <span>(N=2)</span> free-fermion MPS skeleton. As an application of our results, we find a closed form for the disorder parameter in a family of interacting models. Finally, we remark that many of our results use only the Onsager algebra and are not specific to the chiral clock model representation.</p></div>","PeriodicalId":667,"journal":{"name":"Journal of Statistical Physics","volume":"193 6","pages":""},"PeriodicalIF":1.1,"publicationDate":"2026-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13269555/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148269615","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The example, [2], has been recently shown to be incorrect, if taken literally: the point was to suppose that constants of motion, if any besides the energy, would necessarily be smooth functions; and soon later he warned on the dangers implicit in a similar assumption. Fifty years later Fermi wrote a paper attempting to prove that in general a nonlinear system should be ergodic, [3]: but his proof relied again on Boltzmann’s assumption. Thirty-four more years elapsed, and Fermi returned on the problem collaborating with Pasta, Ulam, Tsingou: the surprise was that the considered non linear chain was apparently not following the ergodic hypothesis. In the same year Kolmogorov had proved the conservation of many quasi periodic motions in nonlinear perturbations of integrable systems, [4]: his theorem was considered, already a few years later, a possible explanation of the FPUT work, [5]. This was only the beginning of intense research: here a brief sketch is presented to illustrate the above themes and the connection with the multiscale aspects of the problems, and the “Renormalization group method” intended as a map <span>(mathcal R)</span> whose iterations can be interpreted as successive magnifications, zooming on ever smaller regions of phase space in which motions develop closer and closer to the searched quasi periodic motion of given spectrum.</p></div>","PeriodicalId":667,"journal":{"name":"Journal of Statistical Physics","volume":"193 6","pages":""},"PeriodicalIF":1.2,"publicationDate":"2026-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10955-026-03624-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148237297","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
