Available in PDF, EPUB and Kindle. Book excerpt: Metal‒insulator transitions (MITs) constitute a core subject of fundamental condensed matter research. The localization of conduction electrons occurs in a large variety of materials and engenders intriguing quantum phenomena such as unconventional superconductivity and exotic magnetism. Nearby an MIT, minuscule changes of the interaction strength via chemical substitution, doping, physical pressure, or even disorder can trigger spectacular resistivity changes from zero in a superconductor to infinity in an insulator near T = 0. While approaching an insulating state from the conducting side, deviations from Fermi-liquid transport in bad and strange metals are the rule rather than the exception. As the drosophila of electron‒electron interactions, the Mott MIT receives particular attention from theory as it can be studied using the Hubbard model. On the experimental side, organic charge-transfer salts and transition metal oxides are versatile platforms for working toward solving the puzzles of correlated electron systems. This Special Issue provides a view into the ongoing research endeavors investigating emergent phenomena around MITs.

Book Synopsis The Mott Metal-Insulator Transition by : Florian Gebhard
Download or read book The Mott Metal-Insulator Transition written by Florian Gebhard and published by Springer. This book was released on 2003-07-01 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: Little do we reliably know about the Mott transition, and we are far from a complete understanding of the metal --insulator transition due to electr- electron interactions. Mott summarized his basic ideas on the subject in his wonderful book Metal--Insulator nansitions that first appeared in 1974 11. 1). In his view, a Motk insulator displays a gap for charge-carrying excitations due to electron cowelations, whose importance is expressed by the presence of local magnetic moments regardless of whether or not they are ordered. Since the subject is far from being settled, different opinions on specific aspects of the Mott transition still persist. This book naturally embodies my own understanding of the phenomenon, inspired by the work of the late Sir Kevill Mott. The purpose of this book is twofold: first, to give a detailed presen- tion of the basic theoretical concopts for Mott insulators and, second, to test these ideas against the results from model calculations. For this purpose the Hubbard model and some of its derivatives are best suited. The Hubbard model describes a Mott transition with a mere minimum of tunable par- eters, and various exact statements and even exact solutions exist in certain limiting cases. Exact solutions not only allow us to test our basic ideas, but also help to assess the quality of approxin~ate theories for correlated electron systems.

Available in PDF, EPUB and Kindle. Book excerpt: Here, we use quantum Monte Carlo to determine the magnetic and transport properties of coupled square lattice spin and fermionic planes as a model for a metal-insulator interface. Speci cally, layers of Ising spins with an intra-layer exchange constant J interact with the electronic spins of several adjoining metallic sheets via a coupling JH. Furthermore, when the chemical potential cuts across the band center, that is, at half- filling, the Neel temperature of antiferromagnetic (J> 0) Ising spins is enhanced by the coupling to the metal, while in the ferromagnetic case (J

Book Synopsis Metal-Insulator Transitions and Non-Fermi Liquid Behaviors in 5d Perovskite Iridates by : Abhijit Biswas
Download or read book Metal-Insulator Transitions and Non-Fermi Liquid Behaviors in 5d Perovskite Iridates written by Abhijit Biswas and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Transition metal oxides, in particular, 3d or 4d perovskites, have provided diverse emergent physics that originates from the coupling of various degrees of freedom such as spin, lattice, charge, orbital, and also disorder. 5d perovskites form a distinct class because they have strong spin-orbit coupling that introduces to the system an additional energy scale that is comparable to bandwidth and Coulomb correlation. Consequent new physics includes novel Jeff = 1/2 Mott insulators, metal-insulator transitions, spin liquids, and topological insulators. After highlighting some of the phenomena appearing in the Ruddlesden-Popper iridate series Srn+1IrnO3n+1 (n = 1, 2, and ∞), we focus on the transport properties of perovskite SrIrO3. Using epitaxial thin films on various substrates, we demonstrate that metal-insulator transitions can be induced in perovskite SrIrO3 by reducing its thickness or by imposing compressive strain. The metal-insulator transition driven by thickness reduction is due to disorder, but the metal-insulator transition driven by compressive strain is accompanied by peculiar non-Fermi liquid behaviors, possibly due to the delicate interplay between correlation, disorder, and spin-orbit coupling. We examine various theoretical frameworks to understand the non-Fermi liquid physics and metal-insulator transition that occurs in SrIrO3 and offer the Mott-Anderson-Griffiths scenario as a possible solution.

Book Synopsis Metal-insulator Transition and Quantum Phases in Transition Metal Oxides by : Ru Chen (Physicist)
Download or read book Metal-insulator Transition and Quantum Phases in Transition Metal Oxides written by Ru Chen (Physicist) and published by . This book was released on 2014 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bulk rare earth nickelates, RNiO3(R=rare earth element), display an interesting coexistence of charge and spin ordering and a canonical metal-insulator transition. Guided by experiment and band structure, we introduce and study a phenomenological Landau theory. The unusual magnetic periodicity is simply explained due to Fermi surface nesting of the eg band, and the observed charge order is a secondary order parameter proportional to the degree of orthorhombicity of the material structure. We also predict transport anisotropy resulted from the spin density wave order.
