Curved Light Channels Have Better Coupling
More frequencies of light can pass between two coupled wavy waveguides than between two coupled straight ones, something that could allow for more flexible designs of optics-based circuits on silicon chips. Continue reading
Extra-Stable Light Produced by Levitated Nanoparticle
A trapped nanoparticle interacting with a laser provides a simple way to generate squeezed light, which has an unusually low level of fluctuations. Read more in APS Physics…
Defects Control Silica’s Viscosity
The quirky temperature dependence of liquid silica’s viscosity comes from the liquid equivalent of crystal defects, according to new simulations. Continue reading

Mirror Image Pinpoints a Nanoparticle’s Position
A scattered laser beam’s interaction with itself creates a motion-detection method precise enough to determine whether a trapped particle is in its ground state. Continue reading
Martian Rocks Produced Bio-Friendly Gas Long Ago
Iron-rich rocks in Minnesota give a proxy view into how aqueous interactions with Martian rocks could have shaped that planet’s early environment Continue reading
Pore Collapse Leads to Universal Banded Patterns
A model attributes the propagating bands that appear in a compressed porous medium to structural changes alone. Continue reading
A Liquid Method to Prepare Ion Beams
A liquid-metal jet can strip electrons from a high-intensity, accelerator-based ion beam, increasing the beam’s charge and enhancing accelerator performance. Continue reading
