One dimensional lattice gases with rapidly decreasing interaction
Tóm tắt
We consider the pressure and the correlation functions of a one dimensional lattice gas in which the mutual interaction decreases as r exp-n
t, (r, t>0), when the interparticle distance n→∞. We prove that such a system cannot show phase transitions of order k≧1 in the sense that the pressure and the correlation functions are infinitely differentiable with respect to any relevant parameter (such as the temperature or the chemical potential).
