This transition is controlled by a deformation parameter ε, which modifies the boundary shape from circular, corresponding to ε=0 and an integrable dynamics, to oval for ε≠0, where nonintegrability emerges. The deformation of the circular billiard gives rise to a chaotic layer that develops along a well-defined stripe in phase space. By introducing a set of transformations that isolate this chaotic stripe, we characterize the diffusive spreading of ensembles of trajectories and identify an observable, ω_{rms,sat}, which plays the role of an order parameter for the transition. For small deformations, the saturation value of the diffusion obeys the scaling law ω_{rms,sat}∝ε^{α[over ̃]}, with a critical exponent α[over ̃]=0.507(2), vanishing continuously as ε→0. The associated susceptibility, χ=dω_{rms,sat}/dε, diverges in the same limit, signaling the presence of critical behavior analogous to that observed in second-order (continuous) phase transitions in statistical mechanics.","PeriodicalId":48698,"journal":{"name":"Physical Review E","volume":"113 5-1","pages":"054220"},"PeriodicalIF":2.5,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148279511","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 influence of different ingredients, such as the contact between thermal baths (simultaneous versus not simultaneous contact), the coupling between them (equal or different couplings), and the topology of interactions (all-to-all versus local interactions) is investigated. Closed expressions for transition lines are obtained, expressed by a linear combination of interaction energies times reciprocal temperatures for the simultaneous thermal contact baths and deviates from it when the contact is not simultaneous. The interplay between performance and dissipation is investigated under different conditions, giving rise to a richness of operation regimes, such as the heat engine and heat pump. The relationship between thermodynamic quantities (power, efficiency, and dissipation) allows a careful choice of parameters to ensure the desirable compromise between them. Finally, the influence of different interactions energies [Ising, Potts versus Blume-Emery-Griffiths (BEG)-like] are investigated, revealing that Potts interactions, in general, present superior performances than BEG ones.","PeriodicalId":48698,"journal":{"name":"Physical Review E","volume":"113 5-1","pages":"054118"},"PeriodicalIF":2.5,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148279494","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 each protocol, we derive closed-form expressions for the target qubit's asymptotic polarization and explicitly incorporate the work performed by HBAC into the coefficient of performance (COP). We further quantify the thermodynamic cost of the HBAC stroke and Landauer's bound for both protocols. Our analytical COP curves reveal parameter regimes where the AQOR surpasses the conventional Otto refrigerator. Furthermore, we show that, by tuning the auxiliary qubit's transition frequency and adjusting external control parameters, both protocols achieve enhanced COP and extend the operational window across a wider range of bath temperature differences. Therefore, the AQORs present a tradeoff between achieving high performance in specific regimes and maintaining enhanced applicability. These results demonstrate that algorithmic cooling can be seamlessly integrated into Otto cycles to realize quantum thermal machines with improved practicality on near-term hardware.","PeriodicalId":48698,"journal":{"name":"Physical Review E","volume":"113 5-1","pages":"054112"},"PeriodicalIF":2.5,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148279501","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}

It is also of relevance for solution-phase transport in nanoporous materials, and in particular for catalytic conversion reactions where high yield requires that product species can efficiently pass reactant species to exit the pores. We analyze a two-dimensional model with nonoverlapping circular and discorectangular species confined to a rectangular channel, and where passing is mediated by Brownian dynamics in an implicit solvent. For narrower channels where passing is still possible, the discorectangle must align with the channel to pass the circular species. Behavior of the passing propensity, P, can be assessed by strongly damped Langevin simulations, or within an equivalent Fokker-Planck equation (FPE) formalism. The latter corresponds to a diffusion problem in a \"higher-dimensional channel\" with a constriction. We assess the variation of the passing propensity, P, for a broad range of channel width including its scaling just above the threshold where passing is sterically blocked. Analysis of P versus the rotational diffusion coefficient D_{r} of the discorectangle reveals a significant decrease in P for lower D_{r} for moderate channel width. This prompts a direct analysis of the regime where D_{r}→0, for which the FPE can be reduced to a three-dimensional diffusion problem, precise analysis of which is facilitated by adaptive-mesh finite element methods. The dependence of P on the aspect ratio of the discorectangle is also assessed.","PeriodicalId":48698,"journal":{"name":"Physical Review E","volume":"113 5-1","pages":"054115"},"PeriodicalIF":2.5,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148279523","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}

Using the Fourier-Kontorovich-Lebedev transform, we solve the Laplace equation for the concentration field in the diffusion-dominated regime. The method of images is employed to obtain the first and second reflections of the concentration field, accounting for both monopole and dipole contributions of the particle's surface activity. Based on these results, we derive leading-order expressions for the self-induced phoretic velocity in the far-field limit and examine how it varies with the wedge opening angle and the particle's position within the domain. We focus on the contributions to the phoretic velocities arising from phoretic interactions, without accounting for hydrodynamic effects. Our findings reveal that the wedge geometry significantly affects both the magnitude and direction of particle motion. Our study provides a systematic framework for calculating the contributions to the phoretic velocity arising from concentration disturbances near corners, with implications for microfluidic design and control of autophoretic particles in confined geometries.","PeriodicalId":48698,"journal":{"name":"Physical Review E","volume":"113 5-2","pages":"055414"},"PeriodicalIF":2.5,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148279526","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 process involves the interaction of low-density ablated plasmas, which can give rise to weakly collisional shocks characterized by the Knudsen number Kn on the order of 1. The Knudsen number highlights the importance of kinetic effects. Preliminary investigations have demonstrated that the kinetic effects associated with weakly collisional shocks significantly impact the efficiency of the ICF process. The study explores the development and structural properties of weakly collisional shocks in hohlraums, focusing on ion mixing and separation in multicomponent plasmas, based on large-scale kinetic simulations. Key findings include the behavior of ions and electrons, which is different from strongly collisional shocks in hydrodynamic theory. The influence of charge-to-mass ratios on ion species separation results in two subshocks and deviations in hydrogen ion concentration from hydrodynamic predictions. The effects of weakly collisional shocks on electron and ion distributions are crucial for understanding laser energy coupling and improving diagnostics. Increased collision frequency could transition shock wave physical behavior from kinetically dominated to fluid-dominated. It further clarifies the impact of these shocks on electron and ion kinetics, providing valuable insights for future research in ICF and astrophysics.","PeriodicalId":48698,"journal":{"name":"Physical Review E","volume":"113 5-2","pages":"055206"},"PeriodicalIF":2.5,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148279434","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}
