Tīmeklis2011. gada 19. nov. · 摘要: 以双层耦合复金兹堡-朗道 (Ginzburg-Landau)方程系统为时空模型, 研究了其中的模螺旋波, 讨论了这种特殊波动现象的稳定条件和相关影响因素. 模螺旋波与该类时空系统中常见的相螺旋波相比, 其中心不存在缺陷点, 同时仅在其变量的振幅部分 (而非相位部分) 表现为螺旋结构. 本文通过数值方法研究了耦合复金兹堡-朗 … TīmeklisIn 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 superconductors without examining their … 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, while for Type I superconductors it is of first order, as demonstrated by … Skatīt vairāk The Ginzburg–Landau functional can be formulated in the general setting of a complex vector bundle over a compact Riemannian manifold. This is the same functional as given above, transposed to the notation commonly used in Riemannian … Skatīt vairāk Consider a homogeneous superconductor where there is no superconducting current and the equation for ψ simplifies to: This equation … 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 phase), it is given by while for T < Tc … Skatīt vairāk In the original paper Ginzburg and Landau observed the existence of two types of superconductors depending on the energy of the interface … Skatīt vairāk When the manifold $${\displaystyle M}$$ is a Riemann surface $${\displaystyle M=\Sigma }$$, the functional can be re-written so as to explicitly show self-duality.
