d维磁卡罗尔解构成(d+1)维母体洛伦兹理论解的一致截断,对于规范理论, Sucheta IssueVolume: 2026-02-26 Abstract: We derive Carrollian field theories via null reduction from Lorentzian light-cone actions in Minkowski spacetime. By suitably deforming the light-cone action, from which both magnetic and electric Carroll actions can be obtained in one lower dimension. Through a canonical analysis, we show that the second-class constraints usually found in Lorentzian light-cone theories are absent for these deformed Bargmann-invariant actions. We demonstrate the procedure for theories with and without gauge symmetry. Notably,创刊于2010年,隶属于施普林格自然出版集团,进一步论证表明,。
研究组还阐明了光锥规范条件在导出卡罗尔理论中的关键作用。
通过适当形变光锥作用量。
值得注意的是,这些形变后的巴格曼不变作用量不存在洛伦兹光锥理论中常见的第二类约束, 本期文章:《高能物理杂志》:Online/在线发表 近日,相关论文发表在2026年2月26日出版的《高能物理杂志》上, 研究组分别演示了有无规范对称性理论的推导过程, providing an effective description of light-cone dynamics near a null hypersurface. For gauge theories,而电卡罗尔部分的获得则必须借助形变。
the deformation is essential to obtain the electric Carroll sector. We further argue that magnetic Carroll solutions in d dimensions represent a consistent truncation of the solutions of the (d + 1)-dimensional Lorentzian parent theory,法国国家科学研究中心Sucheta Majumdar团队研究了洛伦兹光锥理论中的卡罗尔推论,磁卡罗尔部分可直接从原始洛伦兹作用量导出。
