TīmeklisDavid Tong: Lectures on the Quantum Hall Effect. This is a course on the quantum Hall effect, given in TIFR, Mumbai. The first four chapters require only basic quantum mechanics; the final two chapters need techniques from quantum field theory. The full lecture notes are around 230 pages. Tīmeklis类似于Landau二级相变理论，考虑序参量的二次，四次项及空间涨落二次项，在为能，可以写出常规超导的自由能其中载流子为Cooper对由变分法 可得两个方程称为 Ginzburg-Landau方程考虑空间尺度足够大的导体，忽略序参量的空间涨落，同时在无磁场环境下解得 可以看出正常态序参量满足U(1)规范变换 ...
Landau-Ginzburg模型的Floer理论 - 中国博士学位论文全文数据库
In physics, Ginzburg–Landau theory, often called Landau–Ginzburg theory, named after Vitaly Ginzburg and Lev Landau, is a mathematical physical theory used to describe superconductivity. In its initial form, it was postulated as a phenomenological model which could describe type-I … Skatīt vairāk Based on Landau's previously established theory of second-order phase transitions, Ginzburg and Landau argued that the free energy, F, of a superconductor near the superconducting transition can be expressed in … Skatīt vairāk The phase transition from the normal state is of second order for Type II superconductors, taking into account fluctuations, as demonstrated by Dasgupta and Halperin, … Skatīt vairāk The Ginzburg–Landau functional can be formulated in the general setting of a complex vector bundle over a compact Riemannian manifold Skatīt vairāk When the manifold $${\displaystyle M}$$ is a Riemann surface $${\displaystyle M=\Sigma }$$, the functional can be re-written so as to … Skatīt vairāk Consider a homogeneous superconductor where there is no superconducting current and the equation for ψ simplifies to: This equation has a trivial solution: ψ = 0. This … Skatīt vairāk The Ginzburg–Landau equations predicted two new characteristic lengths in a superconductor. The first characteristic length was termed coherence length, ξ. For T > Tc (normal … Skatīt vairāk In the original paper Ginzburg and Landau observed the existence of two types of superconductors depending on the energy of the interface between the normal and superconducting states. The Meissner state breaks down when the applied magnetic field is … Skatīt vairāk Tīmeklis金兹堡-朗道理论 (GLTheory)是一种重要的唯象超导理论 (1950)。 与London方程及Pippard非局域理论相比较，GL理论独到之处是可以处理强磁场和超导电子密度在空 … shares_outstanding
