(1+1)维$φ^6$模型中的扭结相互作用

Kink interactions in the (1+1)-dimensional $φ^6$ model

Vakhid A. Gani, Alexander E. Kudryavtsev, Mariya A. Lizunova

摘要:

在集体坐标近似下研究了(1+1)维$φ^6$模型中的扭折散射过程。我们发现临界值的碰撞扭结的初始速度。这些临界速度区分了不同的碰撞状态。$φ^6$模型的精确运动方程也在相同的初始条件下数值求解。我们讨论了集体坐标近似的优点和缺点,并概述了其适用范围。在扭结碰撞中还观察到共振现象和所谓的逃逸窗口。

英文摘要:

We study kink scattering processes in the (1+1)-dimensional $φ^6$ model in the framework of the collective coordinate approximation. We find critical values of the initial velocities of the colliding kinks. These critical velocities distinguish different regimes of collisions. The exact equation of motion for the $φ^6$ model is also solved numerically with the same initial conditions. We discuss advantages and disadvantages of the collective coordinate approximation, and also outline its applicability limits. Resonance phenomena and the so-called escape windows are also observed in the kink collisions.
