TL;DR: In this paper, an effective field theory for dissipative fluids which governs the dynamics of long-lived gapless modes associated with conserved quantities is presented. But the theory is restricted to the case of Gapless modes.
Abstract: We develop an effective field theory for dissipative fluids which governs the dynamics of long-lived gapless modes associated with conserved quantities. The resulting theory gives a path integral formulation of fluctuating hydrodynamics which systematically incorporates nonlinear interactions of noises. The dynamical variables are mappings between a "fluid spacetime" and the physical spacetime and an essential aspect of our formulation is to identify the appropriate symmetries in the fluid spacetime. The theory applies to nonlinear disturbances around a general density matrix. For a thermal density matrix, we require an additional $Z_2$ symmetry, to which we refer as the local KMS condition. This leads to the standard constraints of hydrodynamics, as well as a nonlinear generalization of the Onsager relations. It also leads to an emergent supersymmetry in the classical statistical regime, and a higher derivative deformation of supersymmetry in the full quantum regime.

TL;DR: In this article, it was shown that all higher dimensional Kerr-NUT-AdS solutions of the Einstein equations admit a universal Killing-Yano tensor, which is called the universal tensor tensor.
Abstract: It is well known that 4-dimensional Kerr-NUT-AdS spacetime possesses the hidden symmetry associated with the Killing-Yano tensor. This tensor is "universal" in the sense that there exist coordinates where it does not depend on any of the free parameters of the metric. Recently the general higher dimensional Kerr-NUT-AdS solutions of the Einstein equations were obtained. We demonstrate that all these metrics with arbitrary rotation and NUT parameters admit a universal Killing-Yano tensor. We give an explicit presentation of the Killing-Yano and Killing tensors and briefly discuss their properties.

TL;DR: In this article, a consistent extension of the SIMP models with dark mesons by including a dark U(1)D gauge symmetry was considered, and it was shown how much complementary the additive SIMP constraints on the parameters of the dark photon are for current experimental searches for dark photon.
