Nettet3. des. 2010 · Systems of two coupled bosonic species are studied using mean field theory and the quantum Monte Carlo method. The phase diagram is characterized on the basis of both the mobility of the particles (Mott insulating or superfluid) and whether or not the system is magnetic (different populations for the two species). The phase diagram is … The theory was first proposed by Nevill Francis Mott in a 1949 paper. Mott also wrote a review of the subject (with a good overview) in 1968. The subject has been thoroughly reviewed in a comprehensive paper by Imada, Fujimori and Tokura. A recent proposal of a "Griffiths-like phase close to the Mott transition" has been reported in the literature. brain global alphathon

Nettet1. mar. 2024 · Before and after the Mott phase transition, the transmissivity of TM mode dropped from 74.52% (“ON” state) to 4.07% (“OFF” state). Here, we use modulation depth (MD) to represent the modulation effect of the all-optical switch to the light confined in the waveguide, and use the insertion loss (IL) to further quantify the loss of light passing … Nettet10. sep. 2024 · DFT + DMFT results reveal the existence of a site-selective Mott phase at V = 0.71 V 0 (b), in which the 3 d electrons of only half of the Fe sites (right: B sites) are metallic, while the other Fe (left: A sites) remain insulating. For V = 0.97 V 0 (6 GPa), we obtain a conventional Mott insulating phase in which both the Fe A and B sublattices ... 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 interactions, which are … 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 phenomena in high-temperature superconductivity, for example. Se mer Mottism denotes the additional ingredient, aside from antiferromagnetic ordering, which is necessary to fully describe a Mott insulator.
