Physics is the search for and application of rules that can help us understand and predict the world around us. Central to physics are ideas such as energy, mass, particles and waves. Physics attempts to both answer philosophical questions about the nature of the universe and provide solutions to technological problems.
Excitons are bound electron–hole pairs that are usually either tightly bound or spread across a material. Signatures of hybrid excitons that mix both characters have now been observed at organic–semiconductor interfaces.
A recent study proposes efficient numerical algorithms to reduce the required computational resources for solving the edge states in large-scale photonic or acoustic structures.
The second law of thermodynamics says that entropy may only ever increase during the conversion of one physical state into another. Finding an analogous quantity to characterize the conversion of entangled quantum states has been a rollercoaster ride.
Unambiguous identification of double-strangeness hypernuclei is a challenging task in nuclear physics. Here, the AUs demonstrate identification of 13ΛΛ-B hypernuclei from an AI pipeline applied to the analysis of nuclear emulsion data from the JPARC-E07 experiment.
A study in Optics Express reports the design of a simple dielectric metasurface structure composed of lithium niobate defect disks that enhances the generation of entangled photon pairs through spontaneous parametric down-conversion.

A paper in Optica shows how sound can be used to determine properties of an optical pulse.
