论文摘要
在违反理论的自发性洛伦兹的背景下，对微疗法和能量积极条件的基本问题很重要。我们为自发的洛伦兹（Lorentz）违反术语和经典等效的载体理论从分散关系和繁殖器中检查了自由级别2反对称张量场的微库性和能量阳性条件，并发现两种理论会导致不同的条件。尽管反对称张量理论满足了能量阳性条件，并且可以满足特定真空价值选择的微库性条件，但矢量理论既违反了能量阳性和微疗法条件。
The fundamental issues of microcausality and energy positivity conditions are important to be investigated in the context of spontaneous Lorentz violating theories. We check the microcausality and energy positivity conditions for a free rank-2 antisymmetric tensor field with spontaneous Lorentz violating term and a classically equivalent vector theory from dispersion relations and propagators, and find that the two theories lead to different conditions. While the antisymmetric tensor theory satisfies energy positivity condition and can satisfy microcausality condition for a particular choice of vacuum value, the vector theory violates both energy positivity and microcausality conditions.
