循环局部能量输入下的稳态储能
Energy Storage in Steady States under Cyclic Local Energy Input
摘要：
利用数值模拟的方法研究了在外部循环能量供给下晶格系统的周期稳定态。我们考虑不同的协议，循环能源供应和检查的能量存储。在相同的能流下，我们发现储存的能量取决于供应的细节、供应的周期和幅度。此外，我们引入一个绝热壁作为内部约束的晶格和检查存储的能量相对于不同位置的内部约束。我们发现受约束系统的储能比无约束系统的储能大。我们还观察到，与小的和频繁的输送相比，系统通过大的和稀有的能量输送储存更多的能量。
英文摘要：
We study periodic steady states of a lattice system under external cyclic energy supply using simulation. We consider different protocols for cyclic energy supply and examine the energy storage. Under the same energy flux, we found that the stored energy depends on the details of the supply, period and amplitude of the supply. Further, we introduce an adiabatic wall as internal constrain into the lattice and examine the stored energy with respect to different positions of the internal constrain. We found that the stored energy for constrained systems are larger than their unconstrained counterpart. We also observe that the system stores more energy through large and rare energy delivery, comparing to small and frequent delivery.
