分数量子霍尔效应模型能谱一致性

The spectrum consistency of fractional quantum Hall effect model

O. M. Del Cima, L. S. Lima, E. S. Miranda

AI总结:

分析了三维三费米子族$U(1)\ imes U(1)$量子电动力学的能谱一致性,发现原作用量因负范数态违反幺正性,通过重新用基本规范场表述消除虚假自由度,使模型可安全量子化。

摘要:

分析了三时空维度下三费米子族$U(1)\ imes U(1)$量子电动力学的能谱一致性[Phys. Rev. Lett. 124 (2020) 131601]。已验证原提出的作用量因能谱中存在负范数态,违反了规范场扇区的幺正性一致性条件。然而,通过适当设定基本规范场解决了该问题,用基本场重写的作用量无任何虚假自由度,模型现可安全进行进一步量子化。

英文摘要:

The spectrum consistency of the three fermion family $U(1)\times U(1)$ quantum electrodynamics in three space-time dimensions [Phys. Rev. Lett. 124 (2020) 131601] is analyzed. It has been verified that the originally proposed action violates the unitarity consistency condition in the gauge field sector by exhibiting negative norm states in the spectrum. However, the cure came through the fundamental gauge fields properly settled, consequently, the action rewritten in terms of those fundamental fields shows to be free from any spurious degrees of freedom, and the model now becomes safe for further quantization.
