洛伦兹不变性（LIV）的可能违反可以产生真空双折射，这导致来自远源的线偏振光的偏振平面的频率依赖性旋转。本文试图在天体物理源的偏振光谱数据中寻找由真空双折射引起的线偏振角随频率的变化。我们收集了五个耀变体的多波长偏振测量在不同的光学波段（UBVRI）。考虑到观测到的偏振角的贡献，从两个内在的偏振角和旋转角引起的LIV，并假设的内在偏振角是一个未知的常数，我们得到了新的约束LIV直接拟合的多波长偏振数据的5个耀变体。在这里，我们表明，双折射参数η量化的破坏程度的洛伦兹不变性被限制在-9.63 × 10 − 8 <η <6.55 × 10 − 6在2 σ置信水平的范围内，这是一样好，或代表一个数量级的改进，比以前获得的结果从紫外/光学偏振观测。更强的限制可以通过未来的多波长观测伽马射线能带。
Possible violations of Lorentz invariance (LIV) can produce vacuum birefringence, which results in a frequency-dependent rotation of the polarization plane of linearly polarized light from distant sources. In this paper, we try to search for a frequency-dependent change of the linear polarization angle arising from vacuum birefringence in the spectropolarimetric data of astrophysical sources. We collect five blazars with multiwavelength polarization measurements in different optical bands (UBVRI). Taking into account the observed polarization angle contributions from both the intrinsic polarization angle and the rotation angle induced by LIV, and assuming that the intrinsic polarization angle is an unknown constant, we obtain new constraints on LIV by directly fitting the multiwavelength polarimetric data of the five blazars. Here, we show that the birefringence parameter η quantifying the broken degree of Lorentz invariance is limited to be in the range of −9.63×10−8<η<6.55×10−6 at the 2σ confidence level, which is as good as or represents one order of magnitude improvement over the results previously obtained from ultraviolet/optical polarization observations. Much stronger limits can be obtained by future multiwavelength observations in the gamma-ray energy band.
