标题： Deconfinement phase transitions in external fields

摘要： 我们比较了在存在外部场的情况下，阿贝尔与非阿贝尔格点规范理论的真空动力学。 我们发现，非阿贝尔理论的去禁闭温度取决于一个恒定的阿贝尔色磁场的强度，并最终趋于零。 相反，这种效应并不适用于阿贝尔理论。 我们讨论了这一结果对理解QCD真空的相关性。 显示英文摘要

摘要： We compare vacuum dynamics of abelian versus non abelian lattice gauge theories in presence of external fields. We find that the deconfinement temperature of non abelian theories depends on the strength of a constant abelian chromomagnetic field end eventually goes to zero. On the contrary such an effect is not shared by abelian theories. We argue on the relevance of this result to understand the QCD vacuum.
