NettetElectrochemical capacitors with pure electric double-layer capacitance have so far been largely limited to carbon materials. Conventional metal oxides with faradaic pseudocapacitance substantially suffer from material instability at high temperatures, and thus there is a demand for novel metal oxides exhibit Showcasing recent research in … Nettet16. mar. 2024 · Copper oxide high temperature superconductors universally exhibit multiple forms of electronically ordered phases that break the native translational symmetry of the CuO2 planes. The interplay between these orders and the superconducting ground state, as well as how they arise through doping a Mott insulator, is essential to decode …

"NettetThe Mott-insulating state [Figure 12b,e] was reproduced at half filling, where the energy gap opened at all the k-points. When 17% of the electrons were doped [Figure 12c,f], the noninteracting-like FS emerged. On the other hand, the topology of FS under 17% hole doping [Figure 12a,d] appeared different from the noninteracting case. " - Mott insulating

http://dictionary.sensagent.com/mott%20insulator/en-en/ NettetWe discuss quantum fluctuations of the interface between a superfluid and a Mott-insulating state of ultracold atoms in a trap. The fluctuations of the boundary are due to a new type of surface modes, whose spectrum is similar---but not identical---to classical capillary waves. The corresponding quantum capillary length sets the scale for the …

Nettet17. des. 2024 · Correlated electron states such as the Mott transition arise in theoretical discussions of the behavior of carriers at zero Kelvin. Practical applications of such structure are obviously limited, but Mott insulator behavior has been seen in a variety of materials — notably transition metal oxides — at ambient and higher temperatures. Nettet6. apr. 2024 · Mott insulator NiGa 2 S 4 has attracted much attention because of its elusive magnetic ground state due to the geometric frustration and layered structures. To our knowledge, however, additional studies of the turning properties through external parameters are rather scarce in this system.
