论文摘要
从理论的角度和计算机模拟的角度来看，具有远程相互作用的系统的热力学特性仍然是一个持续的挑战。在这项工作中，我们研究了使用Wang-Landau算法限制在球体内部的模型系统。我们已经计算了状态（CDO），热力学熵和热量曲线的构型密度，并与微型典型的大都市模拟进行了比较，同时显示了如何使用概念（例如构型逆温度）来理解热力学行为的某些方面。在微型蒙特卡洛模拟中，在低能量的低能量上可以看到动力学多性行为，这表明扁平图方法实际上是复杂系统中传统仿真的优越替代方法。
The thermodynamic properties of systems with long-range interactions is still an ongoing challenge, both from the point of view of theory as well as computer simulation. In this work we study a model system, a Coulomb gas confined inside a sphere, by using the Wang-Landau algorithm. We have computed the configurational density of states (CDOS), the thermodynamic entropy and the caloric curve, and compared with microcanonical Metropolis simulations, while showing how concepts such as the configurational inverse temperature can be used to understand some aspects of thermodynamic behavior. A dynamical multistability behavior is seen at low energies in microcanonical Monte Carlo simulations, suggesting that flat-histogram methods are in fact superior alternatives to traditional simulation in complex systems.
