一类新的声孤子

New Kinds of Acoustic Solitons

S. V. Sazonov, N. V. Ustinov

摘要:

我们发现,在Voigt几何条件下,属于孤子方程类的修正sine-Gordon方程描述了超短横向声脉冲通过含顺磁杂质的低温晶体的传播,有效自旋S=1/2.研究了不同类型声孤子对应的应变场和有效自旋的非线性动力学特性。

英文摘要:

We find that the modified sine-Gordon equation belonging to the class of the soliton equations describes the propagation of extremely short transverse acoustic pulses through the low-temperature crystal containing paramagnetic impurities with effective spin S=1/2 in the Voigt geometry case. The features of nonlinear dynamics of strain field and effective spins, which correspond to the different kinds of acoustic solitons, are studied.
