Geometrizing gravity and vice-versa: the force of a formulation [PDF]
, 2009 It is well-known that Newton’s theory of gravity, commonly held to describe a gravitational force, can be recast in a geometrical form: Newton- Cartan theory.

3D Printing Innovations in Polymeric Porous and Patterned Architecture
Advanced Functional Materials, EarlyView.Polymeric foams occupy a unique structural space between dense solids and open networks, where engineered void fraction governs mechanical compliance, thermal resistance, and mass transport. Additive manufacturing now enables precise spatial control over cellular architecture, unlocking designer foam structures across applications spanning crash ...

Presentism and Quantum Gravity [PDF]
, 2001 There is a philosophical tradition of arguing against presentism, the thesis that only presently existing things exist, on the basis of its incompatibility with fundamental physics.

Classical and quantum cosmology in f(T)-gravity theory: A Noether symmetry approach
International Journal of Geometric Methods in Modern Physics, 2021 In the framework of [Formula: see text]-gravity theory, classical and quantum cosmology has been studied in this work for Friedmann Lemaitre Robertson Walker Metric (FLRW) space-time model. The Noether symmetry, a point-like symmetry of the Lagrangian, is used to the physical system and a specific functional form of [Formula: see text] is determined ...

Small free field inflation in higher curvature gravity
Journal of High Energy Physics, 2021 Within General Relativity, a minimally coupled scalar field governed by a quadratic potential is able to produce an accelerated expansion of the universe provided its value and excursion are larger than the Planck scale.

Universal field equations for metric-affine theories of gravity
, 2015 We show that almost all metric-affine theories of gravity yield Einstein field equations with a non-null cosmological constant Lambda. Under certain circumstances and for any dimension, it is also possible to incorporate a Weyl vector field W-mu and ...

Kerr-Schild double copy for Kundt spacetimes of any dimension
Journal of High Energy PhysicsWe show that vacuum type N Kundt spacetimes in an arbitrary dimension admit a Kerr-Schild (KS) double copy. This is mostly done in a coordinate-independent way using the higher-dimensional Newman-Penrose formalism.
