二维Ginzburg-Landau模型的变磁场钉扎

Pinning with a variable magnetic field of the two dimensional Ginzburg-Landau model

Kamel Attar

摘要:

本文在二维有界光滑区域$Ω$中研究了具有钉扎项的变磁场超导体的Ginzburg-Landau能量。假设Ginzburg-Landau参数和磁场强度都很大且为同阶,我们确定了能量最小化的精确渐近公式。这个渐近公式显示了钉扎项的影响。讨论了非平凡解的存在性,证明了第三临界场的渐近性。

英文摘要:

We study the Ginzburg-Landau energy of a superconductor with a variable magnetic field and a pinning term in a bounded smooth two dimensional domain $Ω$. Supposing that the Ginzburg-Landau parameter and the intensity of the magnetic field are large and of the same order, we determine an accurate asymptotic formula for the minimizing energy. This asymptotic formula displays the influence of the pinning term. Also, we discuss the existence of non-trivial solutions and prove some asymptotics of the third critical field.
