AbstractWe analyze the unanalytical structure of metal-insulator transition (MIT) in infinite dimensions. A multiple-valued structure in Green's function and other thermodynamical quantities with respect to the interaction strength U are observed at low temperatures by introducing a transformation into the dynamical mean-field equation of Hubbard model. A complete description of stable, metastable, and unstable phases is established in the regime Uc1(T)< U0 evolves into the second-order one at Uc2(0) for T=0. The phase diagram near MIT is presented.

dc.description.abstractWe analyze the unanalytical structure of metal-insulator transition (MIT) in infinite dimensions. A multiple-valued structure in Green's function and other thermodynamical quantities with respect to the interaction strength U are observed at low temperatures by introducing a transformation into the dynamical mean-field equation of Hubbard model. A complete description of stable, metastable, and unstable phases is established in the regime Uc1(T)< U<Uc2(T). The Maxwell construction is performed to evaluate the MIT line U*(T). We show how the first-order MIT at U*(T) for T>0 evolves into the second-order one at Uc2(0) for T=0. The phase diagram near MIT is presented.en_HK
