1 day ago · A new model of holographic dark energy was suggested within the holographical principle in 2004. However, the new model also had a drawback. The thing is, the dark energy is usually represented as some kind of liquid that homogenously and evenly fills the Universe. A special parameter called square of the sound velocity is used to analyze the ...
3 days ago · Acceleration seems to depend on matter to be accelerated; can there be acceleration without matter to accelerate? Popularly, gravity is just matter "simply" attracted to other matter.
1 day ago · These propagating phenomena are known as gravitational waves. As a gravitational wave passes an observer, that observer will find spacetime distorted by the effects of strain. Distances between objects increase and decrease rhythmically as the wave passes, at a frequency equal to that of the wave.
2 days ago · t. e. General relativity, also known as the general theory of relativity, and as Einstein's theory of gravity, is the geometric theory of gravitation published by Albert Einstein in 1915 and is the current description of gravitation in modern physics.
3 days ago · Electron diffraction is a generic term for phenomena associated with changes in the direction of electron beams due to elastic interactions with atoms.
2 days ago · Flow Matching for Accelerated Simulation of Atomic Transport in Materials. We introduce LiFlow, a generative framework to accelerate molecular dynamics (MD) simulations for crystalline materials that formulates the task as conditional generation of atomic displacements. The model uses flow matching, with a Propagator submodel to generate atomic ...
3 days ago · The forefront of contemporary advances in physics lies in the submicroscopic regime, whether it be in atomic, nuclear, condensed-matter, plasma, or particle physics, or in quantum optics, or even in the study of stellar structure.
