Abstract

The asymptotic structure of three-dimensional Carroll gravity with negative cosmological constant is studied. We formulate a consistent set of boundary conditions preserved by an infinite-dimensional extension of the AdS3 Carroll algebra, which turns out to be isomorphic to a precise generalized BMS3 algebra. This is described by four independent functions of the circle at infinity, generating spatial superrotations, Carroll superboosts, spatial supertranslations and time supertranslations. Remarkably, this asymptotic symmetry algebra contains as subalgebras to BMS3 (generated by spatial superrotations and time supertranslations) and the two-dimensional conformal algebra (spanned by spatial superrotations and spatial supertranslations). We also introduce a new solution — endowed with a Carroll extremal surface — that fulfills this set of asymptotic conditions. By taking advantage of the Chern-Simons formulation of the theory, Carroll thermal properties, obtained from regularity conditions, and entropy of the configuration are also addressed.

卡罗尔引力:渐近对称性和c -热构型
研究了具有负宇宙常数的三维卡罗尔引力的渐近结构。我们构造了由AdS3 Carroll代数的无限维扩展所保持的一组一致的边界条件,该边界条件与精确的广义BMS3代数同构。这由无限远处圆的四个独立函数来描述,产生空间超旋转、卡罗尔超推进、空间超平移和时间超平移。值得注意的是,该渐近对称代数包含BMS3(由空间超旋转和时间超平移生成)和二维共形代数(由空间超旋转和空间超平移生成)的子代数。我们还引入了一种新的解——具有卡罗尔极值曲面——它满足这组渐近条件。利用chen - simons的理论表述,还讨论了从规则条件获得的Carroll热性质和构型的熵。

期刊介绍: The aim of the Journal of High Energy Physics (JHEP) is to ensure fast and efficient online publication tools to the scientific community, while keeping that community in charge of every aspect of the peer-review and publication process in order to ensure the highest quality standards in the journal. Consequently, the Advisory and Editorial Boards, composed of distinguished, active scientists in the field, jointly establish with the Scientific Director the journal''s scientific policy and ensure the scientific quality of accepted articles. JHEP presently encompasses the following areas of theoretical and experimental physics: Collider Physics Underground and Large Array Physics Quantum Field Theory Gauge Field Theories Symmetries String and Brane Theory General Relativity and Gravitation Supersymmetry Mathematical Methods of Physics Mostly Solvable Models Astroparticles Statistical Field Theories Mostly Weak Interactions Mostly Strong Interactions Quantum Field Theory (phenomenology) Strings and Branes Phenomenological Aspects of Supersymmetry Mostly Strong Interactions (phenomenology).
