The effects of the IEC on the phase behavior are systematically analyzed by Monte Carlo simulations using the Wang-Landau (WL) and short-time dynamics (STD) methods. For a fixed identical ratio between exchange and dipolar constants, the temperature-IEC phase diagram at zero external magnetic field is determined. It is demonstrated that the layers reproduce the same low- and high-temperature phases as the bidimensional Ising dipolar model (IDM), namely, stripe domains and a tetragonal liquid phase, respectively. The continuous character of the transition line between these phases is independently confirmed by both WL and STD approaches. Remarkably, a scaling law for the reduced critical temperature is uncovered, characterized by a shift exponent close to the critical susceptibility exponent (γ) of the bidimensional IDM. This finding generalizes the scaling predictions previously reported for the order-disorder transition in short-range Ising bilayers to systems with long-range dipolar interactions. Furthermore, STD results reveal that the critical temperature increases monotonically with the IEC strength, reaching values up to twice the critical temperature of the IDM. This behavior demonstrates a strong IEC-induced enhancement of the thermal stability of the stripe phase, thereby extending the short-range bilayer scenario to the dipolar case. Finally, the estimated critical exponents appear to belong to the universality class of the corresponding bidimensional IDM.","PeriodicalId":48698,"journal":{"name":"Physical Review E","volume":"114 2-1","pages":"024138"},"PeriodicalIF":2.5,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149018349","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}

For a fixed realization of the bulk disorder, full-space partition functions are obtained from the same time-ordered product W(t) through endpoint contractions or a Brownian-weighted initial vector, while the half-space construction modifies only the transfer rule at the absorbing boundary. These choices yield distributions consistent with the standard KPZ subclasses: Tracy-Widom GUE for point-to-point geometry, Tracy-Widom GOE for point-to-line geometry, Tracy-Widom GSE for half-space point-to-point geometry, and Baik-Rains for the stationary line-to-point construction. In all four cases, the free-energy fluctuations grow as t^{1/3}, and the low-order cumulants approach the corresponding universal benchmarks. The matrix-product formulation also provides access to intrinsic spectral observables. For the leading eigenvalue λ_{1}(t), the fluctuations of lnλ_{1}(t) exhibit an intermediate t^{1/3} regime, while the standardized distribution remains distinct from the canonical benchmark laws over the studied time range.","PeriodicalId":48698,"journal":{"name":"Physical Review E","volume":"114 2-1","pages":"024116"},"PeriodicalIF":2.5,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149018341","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}

For many applications, such as interdependent critical infrastructure (ICI) networks, understanding network interdependencies is crucial to anticipate cascading failures and mitigate the risk from disruptions. However, complete network data are often unavailable due to security concerns, and some important interdependent links are revealed only in the aftermath of a disruption. This study formulates and solves a network reconstruction problem to uncover uncertain network interdependencies during disruptions. We propose a scalable nonparametric Bayesian approach to reconstruct the topology of ICI networks from (observed) cascading failures. Metropolis-Hastings (M-H) algorithm coupled with the infrastructure-dependent proposal is employed to increase the efficiency of sampling possible graphs. Numerical results of reconstructing a synthetic system of ICI networks demonstrate that the proposed approach outperforms existing methods in both accuracy and computational time.","PeriodicalId":48698,"journal":{"name":"Physical Review E","volume":"114 2-1","pages":"024308"},"PeriodicalIF":2.5,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149018281","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}

This model undergoes noise-induced transitions between four metastable attractors, forming recurrent but aperiodic \"Escher cycles,\" similar to the cyclic nucleation dynamics observed in the nonreciprocal Ising model. We calculate the quasipotential analytically to first order in nonreciprocality. We characterize it along a one-dimensional reaction coordinate that connects the attractors, and we also obtain the full two-dimensional landscape, at leading order in perturbation theory. The resulting landscapes feature flat regions and extended plateaus, together with nondifferentiable switching lines. These singular structures arise from two geometric mechanisms: the handover of dominance between competing transition paths, and the competition between basins of attraction. The system provides a rare case where the geometry of nonequilibrium rare events can be fully resolved, and a simple analytically tractable example of a quasipotential in more than one coordinate that captures a rich set of nonequilibrium features.","PeriodicalId":48698,"journal":{"name":"Physical Review E","volume":"114 2-1","pages":"024104"},"PeriodicalIF":2.5,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149018437","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}
