Self-accelerated universe induced by repulsive effects as an alternative to dark energy and modified gravities [CL]
A stochastic quasi-classical wavefunction of the Universe from the third quantization procedure [CL]
This week’s image is a snapshot of flow visualisation in the study of direct numerical simulation (DNS) of forced isotropic turbulence.
The first figure depicts a typical chaotic turbulent field, while the second figure, taken some time later, shows the velocity and vorticity vectors more aligned after self-organisation. 101 more words
Join us as we explore some of the latest developments in exactly solved models in statistical mechanics inspired by the remarkable work of Rodney Baxter. His illustrious findings, including the invention of powerful techniques for calculating physical properties and solutions to key models, have provided a platform upon which many further advances in mathematical physics have grown. 167 more words
We present a definition of unsigned magnification in gravitational lensing valid on arbitrary convex normal neighborhoods of time oriented Lorentzian manifolds. This definition is a function defined at any two points along a null geodesic that lie in a convex normal neighborhood, and foregoes the usual notions of lens and source planes in gravitational lensing. 77 more words
