We report the dark-bright soliton can also admit positive effective mass for the Manakov case, by finding two branches of the phases and widths underlying the vector soliton solutions. The positive-mass soliton can evolve stably against noise and weak deviations from the Manakov conditions, and even a line-dark-bright soliton can exist stably in two-dimensional cases with suppressed snake instability, allowing further experimental investigations. When the soliton is driven by a constant force, it diffuses (for negative-mass ones) or splits (for positive-mass ones) as its velocity approaches the maximum moving speed, in contrast to the oscillating ones in nonintegrable cases. The diffusion can be understood by the excitation probabilities of the ground state (bright soliton) to the first excited state in the effective potential well. These results provide important supplements for the vector solitons in integrable cases, and would motivate more discussions on the dispersion relations of soliton in nonlinear coupled systems.","PeriodicalId":48698,"journal":{"name":"Physical Review E","volume":"111 5-1","pages":"054209"},"PeriodicalIF":2.2,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144327339","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}

Prevailing qualitative understanding suggests that the sizes of the fluctuations relative to the size of the basin of attraction in the bifurcation diagram dictate the possibility of noise-driven cellular fate transitions regulated by multistable switches. However, the quantitative relation between the size of basins of attraction and the depth of the wells in the pseudopotential energy of the dynamical systems is unknown. We show that, in multistable switches due to saddle-node bifurcations, the depth of the wells follows power-law scaling with the size of the basins of attraction, with the scaling exponent, α, ranging between 2.5 and 3.0 across various models and parameter combinations. Power-law scaling also holds for the well depth with the distance from the bifurcation point, with the scaling exponent, β, ranging between 1.4 and 1.8. By investigating various models of bi- and tristability with random parameter sampling, we report median scaling exponents of α[over ¯]=2.85±0.12 and β[over ¯]=1.5±0.08. Scaling laws provide a route to determine the well depth, in relative scale, from the bifurcation diagram, bypassing the challenging task of direct calculation of pseudopotential energy in multidimensional dynamical systems.","PeriodicalId":48698,"journal":{"name":"Physical Review E","volume":"111 5-1","pages":"054219"},"PeriodicalIF":2.2,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144327373","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 is based on the rigorous theory of diffusion mass transfer and takes into account the intrinsic kinetics of the evaporation process. Due to its rigor, the presented model does not include the contact angle correction parameter f(θ) that is used in other models. An analysis of the presented model was conducted showing that a sessile droplet can evaporate in the diffusion-kinetic, diffusion, or kinetic regime. Each of these cases was considered separately. The case of sessile droplet evaporation in the constant contact radius mode (pinning) and the case of sessile droplet evaporation in the constant contact angle mode were also considered separately. A comparison of the calculated data obtained within the framework of the presented model with available experimental data on the evaporation kinetics of sessile droplets of ethanol and water into air was carried out. This comparison demonstrated that the presented model perfectly describes experimental data. In addition, this comparison demonstrated that to obtain correct results, a sessile droplet along with its surrounding gas must be isolated from the ambient atmosphere when an experiment to study the evaporation kinetics of the droplet is conducted.","PeriodicalId":48698,"journal":{"name":"Physical Review E","volume":"111 5-2","pages":"055104"},"PeriodicalIF":2.2,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144327435","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}

We have developed an approach to solve physics-based initial value problems using unsupervised machine learning. We propose a deep learning framework that models the dynamics of a variety of mechanical systems through neural networks. Our framework is flexible, allowing us to solve nonlinear, coupled, and chaotic dynamical systems. We demonstrate the effectiveness of our approach on systems including a free particle, a particle in a gravitational field, a classical pendulum, and the Hénon-Heiles system (a pair of coupled harmonic oscillators with a nonlinear perturbation, used in celestial mechanics). Our results show that deep neural networks can successfully approximate solutions to these problems, producing trajectories which conserve physical properties such as energy and those with stationary action. We note that probabilistic activation functions, as defined in this paper, are required to learn any solutions of initial value problems in their strictest sense, and we introduce coupled neural networks to learn solutions of coupled systems.","PeriodicalId":48698,"journal":{"name":"Physical Review E","volume":"111 5-2","pages":"055302"},"PeriodicalIF":2.2,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144327437","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}

To gain insight into the impact of polyadic relationships on dynamical processes on networks, we formulate and study a polyadic voter process, which we call the group-driven voter model (GVM), that incorporates the effects of group dynamics through nonlinear interactions that are subject to a group (i.e., hyperedge) constraint. By examining the competition between nonlinearity and group sizes, we show that the GVM achieves consensus faster than standard voter-model dynamics, with an optimal minimizing exit time. We substantiate this finding by using mean-field theory on annealed uniform hypergraphs with N nodes, for which the exit time scales as AlnN, where the prefactor A depends both on the nonlinearity and on group-constraint factors. Our results reveal how competition between group interactions and nonlinearity shapes GVM dynamics. We thereby highlight the importance of such competing effects in complex systems with polyadic interactions.","PeriodicalId":48698,"journal":{"name":"Physical Review E","volume":"111 5","pages":"L052301"},"PeriodicalIF":2.2,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144327251","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}
