AI总结:
本文研究了二维时空中实标量场模型的kink变换性质,利用特定函数形变从$φ^4$模型构建出具有超指数、幂律和对数等不同渐近行为的孤子新模型,并探讨了形变kink的稳定性势与零模的渐近行为。
摘要:
在这封信中,我们展示了如何为具有不同渐近行为的kink解的理论模型搭建桥梁。我们研究了二维时空中实标量场模型的kink变换性质。我们展示了如何利用特定函数的形变,获得具有不同渐近行为的孤子新模型。特别地,从著名的$φ^4$模型出发,我们获得了具有超指数、超超指数、幂律和对数渐近行为的kink。我们还评论了如何为形变后的kink获得稳定性势和零模的渐近行为。
英文摘要:
In this letter, we show how to build bridges between field-theoretic models that have kink solutions with different asymptotic behavior. We study transformational properties of kinks in models with a real scalar field in two-dimensional space-time. We show how to obtain new models with solitons having different asymptotic behavior, using deformations with specific functions. In particular, starting from the well-known $φ^4$ model, we obtain kinks with super-exponential, super-super-exponential, power-law, and logarithmic asymptotics. We also comment on how asymptotic behavior of stability potential and zero mode can be obtained for deformed kinks.
