摘要翻译：
我们表明负比热的系统可以违反热力学第零定律。通过数值模拟和利用自由能和微正则熵的精确表达式表明，当两个强度参数相同但比热为负的体系热耦合时，它们将经历一个总熵不可逆增加的过程。最终的平衡是两个相，即在两个体系中相同的温度下，子系统具有不同的磁化和内能，但可能不同于初始温度。

英文摘要：
  We show that systems with negative specific heat can violate the zeroth law of thermodynamics. By both numerical simulations and by using exact expressions for free energy and microcanonical entropy it is shown that if two systems with the same intensive parameters but with negative specific heat are thermally coupled, they undergo a process in which the total entropy increases irreversibly. The final equilibrium is such that two phases appear, that is, the subsystems have different magnetizations and internal energies at temperatures which are equal in both systems, but that can be different from the initial temperature.
