论文摘要
基于时间依赖的方程式和有限元建模的Ginzburg-Landau系统，我们提出了与被非渗透环境所包围的超导电线中相位降低的物理学相关的新结果。这些结果是在我们先前报道的与超导环和超导引力检测器传感器有关的方法中获得的。结果表明，相滑中心（PSC）不仅可以有效地产生正热通量。使用适当的设计利用热二极管，PSC可以用作冷冻发动机。在$ t \ sim 1 $ k冷冻剂冷手指上运行，他们可以在不使用$^3 $ HE的情况下达到子kelvin温度。
Based on a time-dependent Ginzburg-Landau system of equations and finite element modeling, we present novel results related with the physics of phase-slippage in superconducting wires surrounded by a non-superconductive environment. These results are obtained within our previously reported approach related to superconducting rings and superconductive gravitational wave detector transducers. It is shown that the phase-slip centers (PSCs) can be effective in originating not only positive but also negative thermal fluxes. With an appropriate design utilizing thermal diodes, PSCs can serve as cryocooling engines. Operating at $T\sim 1$ K cryostat cold-finger, they can achieve sub-Kelvin temperatures without using $^3$He.
