标题： Manipulating phases in many-body interacting systems with subsystem resetting

摘要： 稳定多体系统中的热力学不稳定相——例如抑制帕金森病中病理性的神经元同步或在较宽温度范围内维持磁有序——仍然是一个持续的挑战。 在传统方法中，这些相位通过干预整个系统组分的动力学或者引入额外相互作用来实现稳定。 在这里，我们提出了一种迄今为止未被探索过的替代方案——子系统重置，即通过对系统的一部分动力学进行干预（且这种干预只是偶尔在时间上进行），通过将其状态重置到重置构型来实现。 仅仅调整几个参数，例如重置构型的性质和重置子系统的大小，就可以对裸动力学的相图实现显著且稳健的控制。 我们证明了这些普遍效应涵盖了广泛的场景，包括平衡与非平衡、平均场和非平均场动力学，以及存在和不存在淬火无序的情况。 尽管记忆效应带来了挑战，我们仍然得到了明确的解析预测，并通过模拟验证了这些预测。 显示英文摘要

摘要： Stabilizing thermodynamically unstable phases in many-body systems -- such as suppressing pathological neuronal synchronization in Parkinson's disease or maintaining magnetic order across broad temperature ranges -- remains a persistent challenge. In traditional approaches, such phases are stabilized through intervening in the dynamics of all system constituents or introducing additional interactions. Here, we offer a hitherto-unexplored alternative -- subsystem resetting, whereby intervention in the dynamics of only a part of the system, and that too only occasionally in time, is implemented through resetting its state to a reset configuration. Just playing with a few parameters, e.g., the nature of the reset configuration and the size of the reset subsystem, one achieves a remarkable and robust control over the phase diagram of the bare dynamics. We demonstrate that these universal effects span a wide variety of scenarios, including equilibrium and non-equilibrium, mean-field and non-mean-field dynamics, with and without quenched disorder. Despite the challenges posed by memory effects, we obtain explicit analytical predictions, validated by simulations.
