标题： Pseudoperiodic Spherical Boundary Conditions: Efficient And Isotropic 3D Particle Simulations Without Lattice Artifacts

摘要： 周期性边界条件（PBC）引入了众所周知的晶格伪影。我们提出了一种新的伪周期球形边界条件（SBC），它具有完美的各向同性。通过详细的比较模拟，我们证明SBC消除了PBC固有的结构和动态各向异性。对于这些伪影最显著的拥挤系统，我们的方法在计算上也比标准最小图像约定实现更高效。这确立了SBC作为模拟各向同性物质的一种强大且高保真度的替代方法。 显示英文摘要

摘要： Periodic Boundary Conditions (PBC) introduce well-known lattice artifacts. We present a novel Pseudoperiodic Spherical Boundary Condition (SBC) that is perfectly isotropic. Through detailed comparative simulations, we demonstrate that SBC eliminates the structural and dynamic anisotropy inherent to PBC. For the crowded systems where these artifacts are most prominent, our method is also computationally more efficient than standard Minimum Image Convention implementations. This establishes SBC as a powerful, high-fidelity alternative for simulating isotropic matter.
