The recently discovered charge order is an intrinsic and universal property of cuprate superconductors, however, its microscopic origin remains debated. Here we review briefly the theoretical work about the nature of charge order in cuprate superconductors. In particular, we show that the electron self...
Electron correlations often lead to emergent orders in quantum materials, and one example is the kagome lattice materials where topological states exist in the presence of strong correlations between electrons. This arises from the features of the electronic band structure that are associated with the...
Photoinduced CDW state with topological defects in this material has been discovered from ultrafast electron diffraction and related studies7,28. The non-centrosymmetry in LaTe3 was established from the structure determined by single crystal x-ray crystallography33 as well as from the appearance of ...
Law of Electric Charges The type of force between objects depend on the type of charge the object has –If the charges are the same or if the charges are different from each other –Like/same charges repel away from each other –Different charges attract each other Page 159 – Figure ...
We report the observation of two-fold rotation symmetry in charge density wave (CDW) state in the newly discovered Kagome superconductor CsV$_3$Sb$_5$. Below its CDW transition temperature ($T_{CDW}$), the polarization rotation of the re... Q Wu,ZX Wang,QM Liu,... 被引量: 0发表:...

The results of the calculations for salt 1 based on the crystal structure geometry, neglecting electron–electron correlations, are summarized in Figure 7 and Figure 8 and Table 2. Figure 7. (a) Transfer integrals (TI) network in salt 1 for single conductive organic ET layer in the ...
Long-lived charge carriers are necessary to initiate redox reactions on photocatalyst surfaces. The ideal photocatalyst should have charge carriers with fast mobility and low recombination rates, or good “charge carrier management”. Being able to predi
the physical meaning of the above-determined energy barriers is rather limited due to tunneling effects and the importance of the details of the electron-vibrational structure on the non-radiative transition probabilities63,64,65,66. For that reason, Eqs. (1) and (2) should be regarded as str...
