A crystal, but not as we know it
When we think of crystals, we think of ice, kitchen salt, quartz, and so on—hard solids whose shapes show a regular pattern.

Building an understanding of quantum turbulence from the ground up
Most people only encounter turbulence as an unpleasant feature of air travel, but it's also a notoriously complex problem for physicists and engineers. The same forces that rattle planes are swirling in a glass of water and ...

Testing the universality of the Feynman-Tan relation in interacting Bose gases using high-order Bragg spectra
The Feynman-Tan relation, obtained by combining Feynman energy relation with Tan's two-body contact, explained excitation spectra of strongly interacting quantum gases of 39K atoms. However, whether Feynman-Tan relation is ...

Unique viscometer design integrates a chip-scale GaN optical device with a bendable strip
Traditional viscometers rely on capillary flow, and falling balls are simple and effective means for measuring fluid viscosity over a large range. However, their low measurement throughput and lack of real-time monitoring ...

What physicists can learn from shark intestines
In 1920, inventor Nikola Tesla patented a type of pipe that he called a "valvular conduit," which was built to draw fluid in one direction without any moving parts or added energy, and has applications ranging from soft robotics ...

Conducting supercooled droplet experiments to design and engineer superhydrophobic ice-repellent surfaces
Supercooled droplets can typically freeze on surfaces in nature, and have broad-scale influence on industries where they can adversely impact technical efficiency and reliability. Superhydrophobic surfaces are therefore a ...
The perfect pour: Model predicts beer head features
From creating drinks with distinctive looks to providing aromas for connoisseurs, beer foam is big business. The complex interplay between the components of a beer, the vessel from which it's poured, and the glass it's poured ...

The first model to describe the ways variously sized particles can jam together
The ways in which particles, such as sand or liquid droplets, behave during various mechanical processes is well studied. Typically, in situations where space is constrained, jams can occur, and understanding this can be ...
