Phase competition in strongly correlated materials
Abstract/Contents
- Abstract
- Strongly correlated electron materials display a wide variety of collective electronic phenomena including high-temperature superconductivity, magnetic phases, and charge and orbital ordered states. Rich phase diagrams with multiple competing or cooperating orders often arise, making these materials promising candidates for future device applications. An important step towards being able to understand, predict, and control collective phenomena in strongly correlated systems is to elucidate how these phases relate to each other. This thesis investigates the role of phase competition in strongly correlated materials, utilizing multiple methods and perspectives. One large area of focus in this work is the cuprate high-temperature superconductors, and in particular the relation between the superconducting and pseudogap phases in the hole doped compounds. Through combined experimental and theoretical studies, progress is made towards elucidating the interplay of these orders. The second part of the thesis considers phase competition in strongly correlated systems more generally. Focusing on a model system that incorporates strong electron-electron and electron-phonon interactions, the competition between antiferromagnetic and charge density wave orders is investigated, and evidence for an intervening emergent metallic phase is presented. These findings help clarify how new emergent phases can arise between different phases of matter and the competition between them.
