摘要翻译:
对三维Ising模型的Kallen-Lehman方法在低温和高温下进行了数值分析。结果表明,即使假设最小的对偶破缺,在高温下也可以确定模型的三个参数,与MonteCarlo的结果很好地吻合。在相同的参数下,在低临界温度和接近临界温度下,两者的一致性是令人满意的。本文讨论了如何通过引入更一般的对偶破缺来改进与MonteCarlo结果的一致性。

英文摘要:
A Kallen-Lehman approach to 3D Ising model is analyzed numerically both at low and high temperature. It is shown that, even assuming a minimal duality breaking, one can fix three parameters of the model to get a very good agreement with the MonteCarlo results at high temperatures. With the same parameters the agreement is satisfactory both at low and near critical temperatures. How to improve the agreement with MonteCarlo results by introducing a more general duality breaking is shortly discussed.
