While various methods for controlling active matter have been developed, achieving spontaneous trapping and collective manipulation in complex, variable, noisy environments remains an open challenge. In this paper, we investigate the self-trapping effect and collective motion patterns of chiral active particles induced by a noisy geometric environment in the chiral Vicsek-like model (CVLM). The heterogeneous environment relies on designing the topography by varying the spatial noise intensity, featuring a finite noiseless circular region with radius R_{0}. We identify two key conditions for self-trapping behavior: (i) sufficient interaction radius (r) to break symmetry and enable collective motion, and (ii) chirality (ω) that satisfies the geometric constraints, where stable and effective trapping occurs only if ω>ω_{c}, with ω_{c}≃v/R_{0}. We also analyze how different system parameters influence the fraction of trapped particles (FTP). Furthermore, our system reveals a variety of phase transitions driven by the interplay between ω and r. Interestingly, varying ω uncovers additional phases, such as self-reverting vortices, orbital polarization, and vibrational polarization. Additionally, changes in particle interaction r result in three regimes of particle motion: homogeneous disorder, multiple flocks, and single flocks. These findings may inspire innovative strategies for achieving spontaneous trapping and regulating chiral particles in complex environments.","PeriodicalId":48698,"journal":{"name":"Physical Review E","volume":"111 5-2","pages":"055403"},"PeriodicalIF":2.2,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144327407","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}

In this work, we extend this fundamental scientific question to the plastic regime by exploring the adaptations of crystalline sheets to the large uniaxial mechanical stretching. We reveal the intermittent plastic shear deformations leading to the complete fracture of the sheets wrapping the cylinder. Specifically, systematic investigations of crystalline sheets of varying geometry show that the fracture processes can be classified into defect-free and defective categories depending on the emergence of topological defects. We highlight the characteristic mechanical and geometric patterns in response to the large stretching deformation, including the shear-driven intermittent lattice tilting, the vortex structure in the displacement field, and the emergence of mobile and anchored dislocations as plastic excitations. The effects of noise and initial lattice orientation on the plastic deformation of the stretched crystalline sheet are also discussed. These results advance our understanding of the atomic level on the irreversible plastic instabilities of two-dimensional crystals under large uniaxial stretching and may have potential practical implications in the precise engineering of structural instabilities in packings of covalently bonded particulate systems.","PeriodicalId":48698,"journal":{"name":"Physical Review E","volume":"111 5-2","pages":"055504"},"PeriodicalIF":2.2,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144327413","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 physical features of the oscillatory acceleration and ablation velocity in unperturbed ablative flows display periodic oscillations. As the modulation amplitude or period is increased, the asymmetry of the oscillatory acceleration and ablation velocity becomes more evident, and the peak values of these quantities increase. The numerical solution of the Mathieu equation [R. Betti et al., Phys. Rev. Lett. 71, 3131 (1993)10.1103/PhysRevLett.71.3131] with a fitted acceleration was used to evaluate the behaviors of the oscillatory acceleration. The spatial structure and interfacial evolution of a single-mode ablative Rayleigh-Taylor instability (ARTI) were analyzed for the modulated laser pulses with different modulation amplitudes and periods. It was also observed in a previous work [K. G. Zhao et al., Phys. Rev. E 109, 025213 (2024)10.1103/PhysRevE.109.025213] that the modulated laser exerts a stabilizing influence on the growth of the ARTI in the intermediate- and long-wavelength regions. We found that increasing either the modulation amplitude or period enhances the dynamic stabilization of the ARTI while simultaneously inducing a characteristic destabilization of the parametric instability, which may excite the short-wavelength perturbations through the parametric resonance [G. H. Wolf, Phys. Rev. Lett. 24, 444 (1970)10.1103/PhysRevLett.24.444].","PeriodicalId":48698,"journal":{"name":"Physical Review E","volume":"111 5-2","pages":"055204"},"PeriodicalIF":2.2,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144327415","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}

Rev. D 99, 096001 (2019)2470-001010.1103/PhysRevD.99.096001] we presented an explicit and nonperturbative derivation of the classical radiation reaction force for a cutoff modeled by a special choice of tube of finite radius around the charge trajectories. In this paper, we provide a further, simpler, and so-called reduced radiation reaction model together with a systematic numerical comparison between both the respective radiation reaction forces and the one of Landau-Lifschitz as a reference. We explicitly construct the numerical flow for the new forces and present the numerical integrator used in the simulations, a Gauss-Legendre method adapted for delay equations. As comparison, we consider the cases of a constant electric field, a constant magnetic field, and a plane wave. In all these cases, the deviations between the three force laws are shown to be small. This excellent agreement is an argument for plausibility of both new equations but also means that an experimental differentiation remains hard. Furthermore, we discuss the effect of the tube radius on the trajectories, which turns out to be small in the regarded regimes. We conclude with a comparison of the numerical cost of the three corresponding integrators and argue that, numerically, the integrator of the reduced radiation reaction seems most efficient and the integrator of Landau-Lifschitz least efficient.","PeriodicalId":48698,"journal":{"name":"Physical Review E","volume":"111 5-2","pages":"055309"},"PeriodicalIF":2.2,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144327428","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}
