研究加速和旋转框架中手征对称性破缺的临界温度变化及其影响因素。

摘要:

我们利用低能有效模型研究加速和旋转框架中的手征对称性破缺与恢复。通过分析Rindler坐标中的手征凝聚态,我们显示不同的重整化方案在加速框架中导致不同的结论:在Rindler真空中减去发散项的方案支持与加速无关的临界温度,而在Minkowski真空中减去发散项的方案则表明临界温度增强。我们进一步研究同时具有旋转和加速的系统。发现手征对称性恢复的临界加速度(见第V节定义)随角速度减小,表明加速诱导的热化和旋转诱导的有效化学势存在协同效应。

英文摘要:

We study chiral symmetry breaking and restoration in accelerating and rotating frames using low-energy effective models. By analyzing the chiral condensate in Rindler coordinates, we show that different renormalization schemes lead to distinct conclusions in accelerating frame: the scheme with subtracting divergences in Rindler vacuum supports an acceleration-independent critical temperatures, while the other scheme with subtracting divergences in Minkowski vacuum suggests enhanced critical temperature. We further investigate system with both rotation and acceleration. We find that the critical acceleration (see definition in Section V) for chiral symmetry restoration decreases with angular velocity, indicating cooperative effects from acceleration-induced thermalization and rotation-induced effective chemical potential.
