Abstract We construct the hydrodynamic expansion for a rotating and accelerated medium in a curved space-time, and establish the relationship between the currents generated by the cosmological constant and the acceleration. Then we consider the more general case with a nonzero Weyl tensor, and show the duality between the current in flat space-time and the gravitational axial anomaly. This generalizes the previous derivation to the case with a nonzero Ricci tensor.

The effect of the halogen on the structural, optoelectronic, and luminescent properties of hybrid (1,5-pentanediamine)PbX4 (X = Cl, Br, I) perovskites† The present work reports on the experimental structures, and optoelectronic and luminescence properties of a series of low-dimensional hybrid organic–inorganic (1,5-pentanediamine) PbX4 (X = Cl, Br, I) perovskites.

We consider an accelerated relativistic fluid in four-dimensional (anti–)de Sitter space-time. Analyzing only hydrodynamic equations, we construct the equilibrium stress-energy tensor. We confirm that (A)dS vacuum corresponds to a thermal bath in the accelerated frame with a temperature, depending on the acceleration in a flat higher-dimensional (namely, five-dimensional) space, in which curved space-times are embedded.
