Formation of charge and spin ordering in strongly correlated electron systems
In this review we present results of our theoretical study of charge and spin ordering in strongly correlated electron systems obtained within various generalizations of the Falicov-Kimball model. The primary goal of this study was to identify crucial interactions that lead to the stabilization of v...

In this review we present results of our theoretical study of charge and spin ordering in strongly correlated electron systems obtained within various generalizations of the Falicov-Kimball model. The primary goal of this study was to identify crucial interactions that lead to the stabilization of various types of charge ordering in these systems, like the axial striped ordering, diagonal striped ordering, phase-separated ordering, phase-segregated ordering, etc. Among the major interactions that come into account, we have examined the effect of local Coulomb interaction between localized and itinerant electrons, long-range and correlated hopping of itinerant electrons, long-range Coulomb interaction between localized and itinerant electrons, local Coulomb interaction between itinerant electrons, local Coulomb interaction between localized electrons, spin-dependent interaction between localized and itinerant electrons, both for zero and nonzero temperatures, as well as for doped and undoped systems. Finally, the relevance of resultant solutions for a description of rare-earth and transition-metal compounds is discussed. У цьому оглядi ми представляємо результати наших теоретичних дослiджень зарядового i спiно-вого впорядкування в сильно скорельованих електронних системах, що отриманi в рамках рiзних узагальнень моделi Фалiкова-Кiмбала. Основною метою цього дослiдження було iдентифiкувати ви-рiшальнi взаємодiї, що приводять до стабiлiзацiї рiзних типiв зарядового впорядкування в цих систе-мах, таких як осьове стрiчкове впорядкування, дiагональне стрiчкове впорядкування, фазове роз-шарування, фазова сегрегацiя i т.п. З помiж основних взаємодiй, якi враховують, нами розглядався вплив локальних кулонiвських взаємодiй мiж локалiзованими i колективними електронами, далек-осяжного i скорельованого переносу колективних електронiв, далекосяжної кулонiвської взаємодiї мiж локалiзованими i колективними електронами, локальної кулонiвської взаємодiї мiж колективни-ми електронами, локальної кулонiвської взаємодiї мiж локалiзованими електронами, спiнозалежної взаємодiї мiж локалiзованими i колективними електронами, як при нульовiй так i при ненульовiй температурах, а також для легованих i нелегованих систем. На завершення, обговорюється засто-совнiсть отриманих розв’язкiв для опису сполук рiдкiсноземельних i перехiдних елементiв. 2011 Article Formation of charge and spin ordering in strongly correlated electron systems/ H.
