Conformal properties of soft-operators. Part II. Use of null-states
Journal of High Energy Physics, 2020 Representations of the (Lorentz) conformal group with the soft operators as highest weight vectors have two universal properties, which we clearly state in this paper.

Space-Time Symmetry and Space-Time Ontology
Journal for History of Mathematics, 2015 In spite of various attempts to characterize the ontological status of space-time, Newtonian substantivalism and Leibnizian relationism, what is really at issue in the controversy between the two parties is by no means clear. This essay argues that from the perspective of space-time symmetries, classical space-time can be unambiguously classified as ...

Influence of Form and Structural Features of Open‐Cell Hybrid Foam on the Remanent Magnetic Scanning
Advanced Engineering Materials, EarlyView.Simulations using an equivalent model are performed to improve the understanding of remanent magnetic scanning of hybrid foam samples for coating thickness estimation. The model allows to study the influence of isolated geometrical features such as layer thickness, boundary effects, as well as effects due to the statistical nature of the foams, which ...

Charges and fluxes on (perturbed) non-expanding horizons
Journal of High Energy Physics, 2022 In a companion paper [1] we showed that the symmetry group G $$ \mathfrak{G} $$ of non-expanding horizons (NEHs) is a 1-dimensional extension of the Bondi-Metzner-Sachs group B $$ \mathfrak{B} $$ at I $$ \mathcal{I} $$ +. For each infinitesimal generator

, 2016 Space-time intervals corresponding to different events on the worldline of any ponderable object (for example a clock) are time-like. In consequence, in the analysis of any space-time experiment involving clocks only the region for $c t \ge 0$ between the line $ x = 0$ and the light cone projection $c t = x$ of the $c t$ versus $ x$ Minkowski ...

Advanced Engineering Materials, EarlyView.This study examines the mechanical properties of triply periodic minimal surfaces (TPMS)‐based lattices, analyzing 36 architectures in elastic and plastic regimes. It evaluates the applicability of beam‐based scaling laws to TPMS lattices. Rigidity arises from the alignment of members with the load direction and solid regions preventing rotation.

Discrete Symmetries for Spinor Field in de Sitter Space
, 2005 Discrete symmetries, parity, time reversal, antipodal, and charge conjugation transformations for spinor field in de Sitter space, are presented in the ambient space notation, i.e. in a coordinate independent way.
