Electrostatic Potential in High-Temperature Superconducting Cuprates: Extended Ginzburg-Landau Theory

Figure 2

Variation of vortex lattice structure corresponding to the 𝑠- and 𝑑-wave order parameter components 𝜔_𝑠(𝑥,𝑦) ((a)–(c)) and 𝜔_𝑑(𝑥,𝑦) ((d)–(f)) for different temperatures (𝑡=0.9,0.7,0.5), respectively, calculated by the extended two-order parameter GL theory. Other parameters used for the calculation are GL parameter 𝜅=72, magnetic field induction 𝑏=0.8, and mixed gradient coupling parameter 𝜖_𝑣=0.1, 𝛽_𝑠𝑑=0.
