论文摘要
我们已经研究了有限温度下孤子的真空和热波动能。首先，来自狄拉克海的真空能量是通过索利顿背景场中狄拉克方程的离散和连续能谱的总和来计算的。并且所有差异通过在零温度下的同一重规化方案去除。然后计算在有限温度下的真空能量和在温度依赖性孤子背景下的热波动能。并分析和讨论数值结果。
We have studied the vacuum and thermal fluctuation energies of a soliton at finite temperatures. First the vacuum energy coming from the Dirac sea is calculated by a summation of the discrete and continuum energy spectrum of the Dirac equation in the background field of a soliton. And all the divergences are removed by the same renormalization scheme at zero temperature. Then the vacuum energy and thermal fluctuation energy at finite temperatures in a temperature dependent soliton background are calculated. And the numerical results are analyzed and discussed.
