We explore the scattering dynamics of classical Coulomb-interacting clusters of ions confined to a helical geometry. Ion clusters of equally charged particles constrained to a helix can form many-body bound states; i.e., they exhibit stable...
Kaleidoscopic reorganization of network communities across different scales [0.03%]
网络社区在不同尺度下的多样性重组

Wonhee Jeong et al.
The notion of structural heterogeneity is pervasive in real networks, and their community organization is no exception. Still, a vast majority of community detection methods assume neatly hierarchically organized communities of a characteri...
Energy exchange statistics and fluctuation theorem for nonthermal asymptotic states [0.03%]
非热渐近状态的能量交换统计和涨落定理

Santiago Hernández-Gómez et al.
Energy exchange statistics between two bodies at different thermal equilibria obey the Jarzynski-Wójcik fluctuation theorem. The corresponding energy scale factor is the difference of the inverse temperatures associated to the bodies at eq...

The quantum three-rotor problem concerns the dynamics of three equally massive particles moving on a circle subject to pairwise attractive cosine potentials and can model coupled Josephson junctions. Classically, it displays order-chaos-ord...
Impact of delay on the formation of high-order interactions and structural imbalance [0.03%]
延迟对高阶交互形成和结构不平衡的影响

In real systems, information is never delivered quickly and always will spread with a delay. Because of this delay, an event from the past influences the activities of another entity today, which is no guarantee of direct contact between th...
Effective transport barriers in the biquadratic nontwist map [0.03%]
双边 quadratic nontwist 映射中的有效输运壁垒

Gabriel C Grime et al.
Nontwist area-preserving maps violate the twist condition at specific orbits, resulting in shearless invariant curves that prevent chaotic transport. Plasmas and fluids with nonmonotonic equilibrium profiles may be described using nontwist ...

Take a drinking straw and bend it from its ends. After sufficient bending, the tube buckles forming a kink, where the curvature is localized in a very small area. This instability, known generally as the Brazier effect, is inherent to thin-...
Spontaneous oscillation in collective microswimmers: Insights from a chiral self-propelled rod model [0.03%]
集体微游泳者的自发振荡：手性自推进棒模型的见解
Shuang-Quan He,Xu Yin,Dong Liang et al.
Shuang-Quan He et al.
Active systems exhibit fascinating self-organized structures and rich motility patterns, yet the underlying mechanisms governing their emergence and characteristics remain elusive. Here, we develop a chiral self-propelled rod (CSPR) model w...
Computer simulation study of confined oblate hard ellipsoid liquid crystals: Hard-disk-wall interaction [0.03%]
受限扁椭球硬粒子液晶的计算机模拟研究：硬盘墙相互作用

In this study, instead of an approximate hard Gaussian overlap model, the effects of confinement on a system of oblate hard ellipsoid (OHE) particles interacting with planar substrates through the hard-disk-wall potential (HDW) were studied...
Rheology of nonconvex granular flows based on particle rotational characteristics [0.03%]

Particle shape has a profound impact on the flow behaviors of granular materials, yet effectively incorporating the role of particle shape into granular rheology remains challenging. In this study, we employ three representative types of no...
