Strong coupling limit in asymmetric Hubbard model
After a short review of the physics of the asymmetric Hubbard model, we will examine the strong coupling limit. This limit is performed in a alternative way:the flow equations method.We present the result up to fourth order and compare our results with others to prove that this method gives any more complete description of the physical behaviours
