Time Evolving(时间演变)研究综述
Time Evolving 时间演变 - For the paradigmatic Henon-Heiles system, we use both theoretical and numerical arguments to show that the escaping dynamics is non-ergodic independently of the existence of KAM tori, since the chaotic saddle, in whose vicinity trajectories are more likely to spend a finite amount of time evolving before escaping forever, is not utterly spread over the energy shell. [1] We propose a process in which internal representations of objects spend a certain amount of time evolving before we become aware of them. [2] The Network Analysis unraveled that the significance of sustainability within PPPs has grown over time evolving from traditional developed English-speaking countries to developing countries. [3] It is found that configurational force and polarization have similar evolution laws in both time evolving and space distribution. [4]对于典型的 Henon-Heiles 系统，我们使用理论和数值论证来证明逃逸动力学是非遍历的，与 KAM 托里的存在无关，因为混沌鞍座附近的轨迹更有可能花费有限的数量在永远逃离之前进化的时间，并没有完全散布在能量外壳上。 [1] 我们提出了一个过程，在这个过程中，对象的内部表示在我们意识到它们之前会花费一定的时间来进化。 [2] 网络分析揭示了 PPP 中可持续性的重要性随着时间的推移从传统的发达英语国家演变为发展中国家。 [3] 发现构型力和极化在时间演化和空间分布上具有相似的演化规律。 [4]
Exact Time Evolving 确切的时间演变
We modify the numerically exact time evolving matrix product operator (TEMPO) method, such that it allows the repeated computation of the time evolution of the reduced system density matrix for various sets of control parameters at very low computational cost. [1] In this paper, exact time evolving rules of target range and Doppler are presented for constant acceleration (CA) and coordinated turn (CT) motions in Cartesian coordinates, and two novel pseudo-spectrum based TBD approaches are proposed for effective detection of weak CA and CT targets in range-Doppler plane, respectively. [2]我们修改了数值精确时间演化矩阵乘积算子 (TEMPO) 方法，以便它允许以非常低的计算成本对各种控制参数集的缩减系统密度矩阵的时间演化进行重复计算。 [1] 本文针对笛卡尔坐标中的恒定加速度（CA）和协调转弯（CT）运动，提出了目标距离和多普勒的精确时间演化规则，并提出了两种基于伪谱的新型 TBD 方法，用于有效检测弱 CA 和分别在距离多普勒平面上的 CT 目标。 [2]
time evolving model
We investigate the time-dependence of slab thermal structure using dynamically consistent, time evolving models. [1] Multi-stage time evolving models are common statistical models for biological systems, especially insect populations. [2]我们使用动态一致的时间演化模型研究板坯热结构的时间依赖性。 [1] nan [2]
time evolving block
We analyze the non-equilibrium time evolution of the distribution of the total spin in half of the system and compare the predictions of the semi-semiclassical theory with those of a non-Abelian time evolving block decimation (TEBD) algorithm which exploits the SU(2) symmetry. [1] We simulate coherent driven free dissipative Kerr nonlinear systemnumerically using Euler’smethod by solvingHeisenberg equation ofmotion and time evolving block decimation (TEBD) algorithm, and demonstrate how the numerical results are analogous to classical bistability. [2]time evolving network
We use the time evolution of the aggregate degree of connectivity to measure the time evolving network efficiency in two different scenarios, suggesting a first analysis of the stability of the arising and evolving network structures. [1] Next, we focus on time evolving networks, where existing nodes and links can disappear, and in parallel new nodes and links may be introduced. [2]我们使用聚合连接度的时间演化来衡量两种不同场景下网络效率的时间演化，建议对出现和演化的网络结构的稳定性进行初步分析。 [1] nan [2]
