类致密结构的高温效应

High Temperature Effects on Compactlike Structures

D. Bazeia, E. E. M. Lima, L. Losano

摘要:

在这项工作中,我们研究了在高温下从扭结到牛顿的转变。我们处理一个家庭的模型,由一个真正的标量场与标准的运动学,由一个单一的参数,真正的和积极的控制。该模型族支持扭结解,并且当参数增大到越来越大的值时,解趋于紧凑。我们研究了有限温度下的单圈修正,以了解热效应如何增加有效势。结果表明,对称性在很高的温度下恢复。

英文摘要:

In this work we investigate the transition from kinks to compactons at high temperatures. We deal with a family of models, described by a real scalar field with standard kinematics, controlled by a single parameter, real and positive. The family of models supports kinklike solutions, and the solutions tend to become compact when the parameter increases to larger and larger values. We study the one-loop corrections at finite temperature, to see how the thermal effects add to the effective potential. The results suggest that the symmetry is restored at very high temperatures.
