Artificial Intelligence and Advanced Materials
Advanced Materials, Volume 35, Issue 23, June 8, 2023., 2023 Artificial intelligence in general and machine learning in particular are gaining ever more importance in science and technology. In materials science, they are taking over tedious screening tasks and helping design and discover materials based on both explicit and tacit previous knowledge possessed by the scientist.

Gravitational lensing by charged black hole in regularized 4D Einstein–Gauss–Bonnet gravity
European Physical Journal C: Particles and Fields, 2020 Among the higher curvature gravities, the most extensively studied theory is the so-called Einstein–Gauss–Bonnet (EGB) gravity, whose Lagrangian contains Einstein term with the GB combination of quadratic curvature terms, and the GB term yields ...

Gravitational wave lensing beyond general relativity: Birefringence, echoes, and shadows [PDF]
Physical Review D, 2020 Gravitational waves (GW), as light, are gravitationally lensed by intervening matter, deflecting their trajectories, delaying their arrival and occasionally producing multiple images.

Testing General Relativity with Current Cosmological Data [PDF]
, 2010 Deviations from general relativity, such as could be responsible for the cosmic acceleration, would influence the growth of large scale structure and the deflection of light by that structure.

GRAVITATIONAL LENSING EFFECT ON COSMIC MICROWAVE BACKGROUND ANISOTROPIES: A POWER SPECTRUM APPROACH [PDF]
, 1995 The effect of gravitational lensing on cosmic microwave background (CMB) anisotropies is investigated using the power spectrum approach. The lensing effect can be calculated in any cosmological model by specifying the evolution of gravitational potential.

Parameters estimation and strong gravitational lensing of nonsingular Kerr-Sen black holes [PDF]
, 2020 The recent time witnessed a surge of interest in strong gravitational lensing by black holes is due to the Event Horizon Telescope (EHT) results, which suggest comparing the black hole lensing in both general relativity and heterotic string theory.

Gravitational lensing and modified Newtonian dynamics [PDF]
, 2001 Gravitational lensing is most often used as a tool to investigate the distribution of (dark) matter in the universe, but, if the mass distribution is known a priori, it becomes, at least in principle, a powerful probe of gravity itself.

A Hamiltonian, post-Born, three-dimensional, on-the-fly ray tracing algorithm for gravitational lensing [PDF]
Journal of Cosmology and Astroparticle PhysicsThe analyses of the next generation cosmological surveys demand an accurate, efficient, and differentiable method for simulating the universe and its observables across cosmological volumes. We present Hamiltonian ray tracing (HRT) — the first post-Born (
