研究了强磁场和极电场中量子色动力学的真空性质。我们表明，当一个均匀的电场是瞬间施加在平行于一个强磁场的方向，它诱导的标量和赝标凝聚的时间振荡。这是手征螺旋的时间模拟。振荡起源于集体模式的传播，集体模式受到轴向异常的保护，因此是非耗散的。
Vacuum properties of quantum chromodynamics in strong magnetic and nite electric elds are investigated. We show that when a uniform electric eld is instantaneously applied in the parallel direction to a strong magnetic eld, it induces temporal oscillation of the scalar and pseudoscalar condensates. This is a temporal analog to the chiral spiral. The oscillation originates with the propagation of the collective mode, which is protected by the axial anomaly and thus is nondissipative.
