Phonon negative gravity
WebAug 13, 2024 · Scientists during the study found that the phonons have a tiny mass and thus they move in opposite direction when gravity tugs on them. Krichevsky explained, “To understand how this might work, imagine a normal fluid in which gravity acts downward. Fluid particles will compress the particles below it, so that it’s slightly denser lower down. WebAug 15, 2024 · But no one has suggested that they actually are particles, which means they should not have mass. In this new effort, the researchers suggest the phonon could have …

The terms arise due to nonlinear f(R) functions being treated as energy due to curvature-inspired geometry. As a result, we find the accelerating expansion in the universe, which creates an anti-gravitating negative pressure in it. Some …

They claim that phonons might have negative mass and also have negative gravity. Arxiv – The mass of sound It is usually said that sound waves do not transport mass.
WebJul 23, 2024 · Keep in mind that condensing mode by mode is not enough, as phonon-phonon couplings might be important. For instance, for BaTiO3, if you condense the FE mode along two directions onto the cubic structure, you'll notice the new phase is more energetically favorable. The same occurs if you do it along the 3 directions. $\endgroup$ –
