Unusual low-temperature behavior in the half-filled band of the one-dimensional extended Hubbard model in atomic limit
Unusual low-temperature behavior in the half-filled band of the one-dimensional extended Hubbard model in atomic limit
Recently, a kind of finite-temperature pseudotransition was observed in several quasi-one-dimensional models. In this work, we consider a genuine one-dimensional extended Hubbard model in the atomic limit, influenced by an external magnetic field and with the arbitrary number of particles controlled by the chemical potential. The one-dimensional extended Hubbard model …
