JOURNAL OF STATISTICAL PHYSICS 134(2) 401-423 2009年1月
Recently a novel concise representation of the probability distribution of heat conducting nonequilibrium steady states was derived. The representation is valid to the second order in the "degree of nonequilibrium", and has a very suggestive form ...

It is believed that strong ferromagnetic orders in some solids are generated by subtle interplay between quantum many-body effects and spin-independent Coulomb interactions between electrons. Here we describe our rigorous and constructive approach...
