摘要：
活性物质通过利用自由能驱动其组成智能体自主运动，从而产生多种涌现状态，这些状态与生物过程和无生命功能均相关。以最少控制实现活性材料的最大可重构性，仍是一个理想但富有挑战性的目标。本文采用大规模、智能体分辨模拟，证明仅调节湿式泳动介质的活性，就能够控制其固—液—气相变，随后控制流体相中的层流—湍流转变，从而塑造其涌现图案。这两个逐步出现且此前未见报道的转变，使我们更接近认识活性物质与传统物质之间的相似性。我们的工作复现并调和了关于化学活性系统中看似矛盾的实验观测，呈现了泳动集体动力学的统一图景。这些发现增进了对泳动智能体之间长程多体相互作用的理解，为其非平衡集体行为提供了新见解，并为设计可重构材料提供了潜在指导。
英文摘要：
Active matter drives its constituent agents to move autonomously by harnessing free energy, leading to diverse emergent states with relevance to both biological processes and inanimate functionalities. Achieving maximum reconfigurability of active materials with minimal control remains a desirable yet challenging goal. Here, we employ large-scale, agent-resolved simulations to demonstrate that modulating the activity of a wet phoretic medium alone can govern its solid-liquid-gas phase transitions and, subsequently, laminar-turbulent transitions in fluid phases, thereby shaping its emergent pattern. These two progressively emerging transitions, hitherto unreported, bring us closer to perceiving the parallels between active matter and traditional matter. Our work reproduces and reconciles seemingly conflicting experimental observations on chemically active systems, presenting a unified landscape of phoretic collective dynamics. These findings enhance the understanding of long-range, many-body interactions among phoretic agents, offer new insights into their non-equilibrium collective behaviors, and provide potential guidelines for designing reconfigurable materials.
