具有随机单体活动的平均场单体-二聚体模型。精确解和严格结果

A mean-field monomer-dimer model with random monomer activities. Exact solution and rigorous results

Diego Alberici, Pierluigi Contucci, Emanuele Mingione

摘要:

独立的随机单体活动被认为是一个平均场单体-二聚体模型。在非常一般的条件下的随机性的模型被证明有一个自平均的压力密度,服从可解的变分原理。在热力学极限下精确计算了二聚体密度,并证明其为光滑函数。

英文摘要:

Independent random monomer activities are considered on a mean-feld monomer-dimer model. Under very general conditions on the randomness the model is shown to have a self-averaging pressure density that obeys a solvable variational principle. The dimer density is exactly computed in the thermodynamic limit and shown to be a smooth function.
