New work extends the thermodynamic theory of computation

Every computing system, biological or synthetic, from cells to brains to laptops, has a cost. This isn't the price, which is easy to discern, but an energy cost connected to the work required to run a program and the heat ...

Ultrafast X-ray spectroscopy as a probe of nonequilibrium dynamics in ruthenium complexes

(Phys.org)—Exciting the atoms or molecules of a substance via the use of visible light, or photoexcitation, can play a significant role in a range of energy-conversion processes, such as natural photosynthesis (oxygen from ...

The magnetization dynamics of rare-earth metals and the role of ultrafast magnon generation

Rare-earth magnetism is dominated by localized 4f electrons, relative to inner transition metals (that are mostly comprised of lanthanides) and cannot be directly excited through an optical laser pulse. As a result, ultrafast ...
