[2108.12525] Field induced conducting state in Mott insulator
Nettet14. aug. 2024 · The Mott transition is a classic paradigm in quantum many-body physics, in which electronic interactions can produce an insulating state. By contrast, a nontrivial band-structure topology in condensed matter systems leads to a topological insulator. Here, the authors make a connection between the seemingly disparate physics of these … Nettet5. mar. 2024 · Electrical conductors such as metals, on the other hand, exhibit partially filled energy bands, with empty energy states which the electrons can fill to freely … 高校受験 アプリ 無料 おすすめ

Nettet27. aug. 2024 · Field induced conducting state in Mott insulator. Electron--electron repulsion, on the one hand, can result in bound pair, which has heavy effective mass. … Nettet12. apr. 2024 · The long search for insulating materials that possess low-energy quasiparticles carrying electron's quantum numbers except charge---inspired by the neutral spin-$1/2$ excitations, the so-called spinons, exhibited by Anderson's resonating-valence-bond state---seems to have reached a turning point after the discovery of several Mott … Mott insulators are a class of materials that are expected to conduct electricity according to conventional band theories, but turn out to be insulators (particularly at low temperatures). These insulators fail to be correctly described by band theories of solids due to their strong electron–electron … Se mer Although the band theory of solids had been very successful in describing various electrical properties of materials, in 1937 Jan Hendrik de Boer and Evert Johannes Willem Verwey pointed out that a variety of transition metal oxides predicted … Se mer Mott insulators are of growing interest in advanced physics research, and are not yet fully understood. They have applications in thin-film magnetic heterostructures and the strong correlated … Se mer • Dynamical mean-field theory – method to determine the electronic structure of strongly correlated materials • Electronic band structure – Describes the range of energies of an … Se mer Mottism denotes the additional ingredient, aside from antiferromagnetic ordering, which is necessary to fully describe a Mott insulator. In other words, we might write: antiferromagnetic order + mottism = Mott insulator. Thus, mottism … Se mer 高校受験 いつ
