论文摘要
作用于铁磁孤子的陀螺力反映了旋转的趋势。它的成分随孤子的(广义)速度线性增加。比例系数形成了陀螺张量,这是硫尔陀螺仪的概括。陀螺张量最初是作为辅助数量引入的,事实证明,陀螺仪是一个基本重要性的数学对象,悠久的历史可以追溯到拉格朗日。我们回顾陀螺张量及其历史根源的应用。
The gyroscopic force acting on a ferromagnetic soliton reflects the tendency of spins to precess. Its components increase linearly with (generalized) velocities of the soliton. The proportionality coefficients form the gyroscopic tensor, a generalization of Thiele's gyrovector. Originally introduced as an auxiliary quantity, the gyroscopic tensor turns out to be a mathematical object of fundamental importance with a long history going back to Lagrange. We review the applications of the gyroscopic tensor and its historical roots.
