摘要:

我们研究了虚角速度下的有限温度SU(2)萨维迪模型。采用背景场方法,推导了单圈有效势并分析其实部和虚部。证明虚旋转改变了色磁凝聚和玻利亚科夫圈,并能部分抑制色磁背景的尼尔森-奥尔斯en不稳定性。高温展开表明虚旋转增强了有效耦合,且色磁场对转动惯量有负贡献。

英文摘要:

We investigate the finite-temperature SU(2) Savvidy model under an imaginary angular velocity. Employing the background-field method, we derive the one-loop effective potential and analyze both its real and imaginary parts. We demonstrate that imaginary rotation modifies the chromomagnetic condensate and the Polyakov loop, and can partially suppress the Nielsen-Olesen instability of the chromomagnetic background. Moreover, a high-temperature expansion shows that imaginary rotation strengthens the effective coupling and that the chromomagnetic field induces a negative contribution to the moment of inertia.
