论文摘要
在这项工作中，我们使用熵模拟研究了钟轮模型，以实现能量参数的几个值。彻底分析了$ t \timesμ$相图和基态配置。此外，我们研究了化学势$μ$的不同值作为温度功能的颗粒密度和比热行为。我们还获得了对几个化学电位和温度值的规范概率最大化的配置，从而可以鉴定低密度（$ ldl $）和高密度液体（$ HDL $）阶段，以及在关键区域中。我们发现从$ LDL-HDL_0 $到$ ldl-hdl $共存的二阶过渡范围为$ 0 <μ<1.05503 $。在$ 1.05503 <μ<1.48024 $范围内，$ ldl-hdl_0 $和$ ldl-hdl_0-empty $共存之间的过渡呈现出不连续和连续的过渡特征。最后，价格为$ 1.48024 <μ<1.5 $，$ ldl $和$空$阶段之间的相变是一阶。
In this work, we investigate the Bell-Lavis model using entropic simulations for several values of the energy parameters. The $T\timesμ$ phase diagram and the ground state configurations are analyzed thoroughly. Besides, we examine the particle density and specific heat behavior for different values of the chemical potential $μ$ as functions of temperature. We also obtain configurations that maximize the canonical probability for several values of chemical potential and temperature, enabling the identification of the low density ($LDL$) and high-density liquid ($HDL$) phases, among others, in the critical regions. We found a second-order phase transition from the $LDL-HDL_0$ to $LDL-HDL$ coexistence in the range of $0<μ<1.05503$. In the $1.05503<μ<1.48024$ range, the transition between the $LDL-HDL_0$ and $LDL-HDL_0-empty$ coexistence presents discontinuous and continuous transitions characteristics. Finally, for $1.48024<μ<1.5$, the phase transition between $LDL$ and $empty$ phases is of first-order.
