I have read very interesting article written by Gross, about termostatics. Author described termodynamics from microcanonical ensemble point of view, and particulary he acheive for example description of phase transitions and termodynamic description of small systems like 100 nucleons as well. This had been done without termodynamic limit! His works are accessible on arxiv and on his home page ( try google) [ Mod. note: Since more than one Gross can be found on the arXiv, at least one link would be helpful. [itex]-ik ][/itex] Did You heared about this point of view? Is there elsewhere any serious discussion of this matter? Thanks kazek |

arxiv:http://www.arxiv.org/abs/cond-mat/0206341 As this use microcanonical ensemble there is possibility to describe ensembles in which termodynamic limit cannot be taken, like systems with long range forces like gravitation for example. For that kind of systems termodynamic limit cannot be easely taken so canonical ensemble may be inconsistent with microcanonical one. I am very interested in Your opinion about this matter.
