三次非线性Ginzburg-Landau方程的旅行扭结

Traveling kinks in cubic nonlinear Ginzburg-Landau equations

H. C. Rosu, O. Cornejo-Perez, P. Ojeda-May

摘要:

非线性三次欧拉-拉格朗日运动方程的旅行变量通常来自金兹伯格-朗道自由能泛函经常遇到的几个物理领域。许多作者认为,在过去的阻尼版本,这样的方程与阻尼项增加了手模拟摩擦,由于环境。众所周知,即使在这种阻尼情况下,也可能存在扭结解。通过因式分解的方法,我们提供了几种可能的扭结解的运动方程的非驱动和恒定场驱动的情况下,包括最近推出的Riccati参数扭结,以前没有考虑在这样的上下文中的解析公式。后一个参数控制扭结切换阶段的延迟

英文摘要:

Nonlinear cubic Euler-Lagrange equations of motion in the traveling variable are usually derived from Ginzburg-Landau free energy functionals frequently encountered in several fields of physics. Many authors considered in the past damped versions of such equations with the damping term added by hand simulating the friction due to the environment. It is known that even in this damped case kink solutions can exist. By means of a factorization method, we provide analytic formulas for several possible kink solutions of such equations of motion in the undriven and constant field driven cases, including the recently introduced Riccati parameter kinks which were not considered previously in such a context. The latter parameter controls the delay of the switching stage of the kinks
