Learning from fish and flags to inform new propulsion strategies

Recent research by Andres J. Goza at the University of Illinois at Urbana-Champaign found relationships between frequencies and the passive dynamics at play when vehicles move in air or water toward a better understanding ...

Dielectric metasurfaces for next-generation holograms

Metasurfaces are optically thin metamaterials that can control the wavefront of light completely, although they are primarily used to control the phase of light. In a new report, Adam C. Overvig and colleagues in the departments ...

Neutrons detect elusive Higgs amplitude mode in quantum material

A team led by the Department of Energy's Oak Ridge National Laboratory has used sophisticated neutron scattering techniques to detect an elusive quantum state known as the Higgs amplitude mode in a two-dimensional material.
