论文摘要
提出了一个统一的现象学描述框架，以评估一些最重要的库酸酯超导体的可观察物：pseudogap（pg）$δ_{\ rm pg} $，本地超导量，当型$Δ （CO）参数。最近详细的CO结构和CO波长的测量值$λ_{\ rm co} $是由具有自由能势$ v _ {\ rm gl} $的cahn-hilliard微分方程的解决方案忠实地复制的，该方程会产生交替的小电荷模式。电荷振荡诱导原子波动，可介导与$ v _ {\ rm gl} $振幅成正比的SC对相互作用。本地SC振幅和阶段$θ_i$通过Josephson耦合$ e _ {\ rm j}（r _ {\ rm ij}）$连接，当$ {\ weft <e _ {\ e _ {\ rm j}} \ rm j} \ rim j} \ rm j} \ sim sim _ _ _ _ _ { C} $。波长$λ_{\ rm co} $，$δ_ {\ rm pg} $，$ \ left<δ_{\ rm sc} \ right> $和$ t _ {\ rm c} $计算与各种经验符合各种经验的均匀均匀。
A unified phenomenological description framework is proposed for the evaluation of some of the most important observables of the cuprate superconductors: the pseudogap (PG) $Δ_{\rm PG}$, the local superconducting amplitudes $Δ_{\rm SC}(r_i)$, the critical temperature $T_{\rm c}$ and charge ordering (CO) parameters. Recently detailed measurements of CO structures and CO wavelengths $λ_{\rm CO}$ are faithfully reproduced by solutions of a Cahn-Hilliard differential equation with a free energy potential $V_{\rm GL}$ that produces alternating small charge modulations. The charge oscillations induce atomic fluctuations that mediate the SC pair interaction proportional to the $V_{\rm GL}$ amplitude. The local SC amplitude and phase $θ_i$ are connected by Josephson coupling $E_{\rm J}(r_{\rm ij})$ and the SC long-range order transition occurs when ${\left < E_{\rm J} \right>} \sim k_{\rm B}T_{\rm c}$. The calculated results of the wavelength $λ_{\rm CO}$, $Δ_{\rm PG}$, $\left < Δ_{\rm SC}\right >$ and $T_{\rm c}$ calculations are in good agreement with a variety of experiments.
