Excitons—bound pairs of electrons and an electron hole—are quasiparticles that can arise in solids. While so-called "bright" ...

Recent physics studies have found that light can sometimes flow in unexpected ways, behaving like a so-called "superfluid." ...

Astronomers using the Green Bank Telescope spotted surprisingly cold, dense hydrogen clouds embedded inside the Milky Way’s ...

The spatial transfer function (STF) is important for many acoustic technologies. However, it is not easy to measure STFs at multiple points. We propose a method of estimating the sound field using a ...

Radio frequency (RF) cable assemblies play a crucial role in high-frequency communication systems, and their passive intermodulation (PIM) performance is of paramount importance. In this article, a ...
