6 Oct 2019 | Abstract: | Insulator-metal transition is investigated self-consistently on the
frustrated Shastry-Sutherland lattice in the framework of Slave-Boson
mean-field theory. Due to the presence of quasi-flat band structure
characteristic, the system displays a spin-density-wave (SDW) insulating phase
at the weak doping levels, which is robust against frustration, and it will be
transited into an SDW metallic phase at high doping levels. As further
increasing the doping, the temperature or the frustration on the diagonal
linking bonds, the magnetic order $m$ will be monotonically suppressed,
resulting in the appearance of a paramagnetic metallic phase. Although the
Fermi surface of the SDW metallic phase may be immersed by temperature, the
number of mobile charges is robust against temperature at weak doping levels. | Source: | arXiv, 1910.2385 | Services: | Forum | Review | PDF | Favorites |
