The Newman-Penrose formalism in quadratic gravity

The quadratic gravity constraints are reformulated in terms of the Newman-Penrose-like quantities. In such a frame language, the field equations represent a linear algebraic system for the Ricci tensor components. In principle, a procedure for the combination of the Ricci components with standard geometric identities can be applied in a similar way as in the case of general relativity. These results could serve in various subsequent analyses and physical interpretations of admitted solutions to quadratic gravity. Here, we demonstrate the utility of such an approach by explicitly proving general propositions restricting the spacetime geometry under assumptions on a specific algebraic type of curvature tensors.Comment: 25 pages, to be submitte

The bouncing dynamics of inertial self-propelled particles reveals directional asymmetry

The paper is devoted to the study of experimental conditions for bound states in which active particles are forced by their environment to move forward and backward in a steady oscillatory mode. The realization of this idea in our proposal is carried out by means of a hexbug (a vibrating self-propelled toy robot) confined in a narrow channel bounded by a rigid moving end-wall. The motion modes were studied both experimentally and theoretically. In the theoretical framework, we investigated the one-dimensional single-particle approximation within the Brownian model of active particles with inertia using numerical simulations. The model includes the hexbug's contact with the base plate via tilted flexible legs that provide propulsion. At the same time, the tilting contributes to directional asymmetry of the system. The end-wall velocity was used as an external parameter to influence the bouncing process. After regressing the spatial and temporal statistical characteristics, the simulation satisfactorily reproduced the experimental properties of hexbug motion, mainly due to the considered directional asymmetry
