标题： Quantum flux operators in higher spin theories

摘要： 我们通过将平空间中的玻色型Fronsdal理论约化到未来null无穷远来构建Carroll高自旋场理论。我们将庞加莱通量扩展为生成Carroll微分同胚（即超平移和超旋转）的量子通量算子。这些通量算子在包括一个由高自旋超对偶变换得出的螺旋度通量算子后形成闭合的对称代数。超对偶变换是在未来null无穷远的角依赖变换，它推广了通常的电磁对偶变换。当限制到$s=0,1,2$时，结果与低自旋情况一致。 显示英文摘要

摘要： We construct Carrollian higher spin field theories by reducing the bosonic Fronsdal theories in flat spacetime to future null infinity. We extend the Poincar\'e fluxes to quantum flux operators which generate Carrollian diffeomorphism, namely supertranslation and superrotation. These flux operators form a closed symmetry algebra once including a helicity flux operator which follows from higher spin super-duality transformation. The super-duality transformation is an angle-dependent transformation at future null infinity which generalizes the usual electro-magnetic duality transformation. The results agree with the lower spin cases when restricting to $s=0,1,2$.
