R. L. S. Farias, Rudnei O. Ramos, Dérick S. Rosa

摘要:

研究了有限温度下外加磁场作用下的两个耦合复标量场模型。结果得到的优化微扰理论的非微扰方法的背景下,并与微扰理论和单回路近似中得到的结果进行对比。分析了逆对称性破缺和对称性不可恢复现象的出现。

英文摘要:

A model of two coupled complex scalar fields is studied at finite temperature and under an external magnetic field. The results are obtained in the context of the nonperturbative method of the optimized perturbation theory and contrasted with those obtained in perturbation theory and in the one-loop approximation. The emergence of phenomena related to inverse symmetry breaking and symmetry nonrestoration are analyzed.
