We investigate geometric quantum speed limit of neutrino oscillations in a presence of matter and CP-violation. We show that periodicity in the speed limit present in an unperturbed system becomes damped by interaction with a normal matter and decoherence. We also show that (hypothetical) CP-violation causes enhancement of periodicity and increases amplitude of an oscillating quantum speed limit and can quantify CP-violation.

中微子振荡的几何速度极限

我们研究了在存在物质和CP违反的情况下中微子振荡的几何量子速度极限。我们表明，在不受干扰的系统中存在的速度极限中的周期性会因与正常物质和退相干的相互作用而衰减。我们还表明，（假设的）CP违反会导致周期性增强，并增加振荡量子速度限制的幅度，并且可以量化CP违反。
