Theoretical calculations anchor graphene’s simple optical absorption in its two-dimensional structure instead of its cone-shaped energy bands. Read More »
Converting infrared light to visible light might boost the sensitivity of infrared telescope arrays. Read More »
Cold atomic gases exhibit a phononic analog of the Lamb shift, in which energy levels shift in the presence of the quantum vacuum. Read More »
New Space Station data support a straightforward model of cosmic-ray propagation through the Galaxy but also add to previous signs of undiscovered cosmic-ray sources such as dark matter. Read More »
Undergrads attending the PhysCon meeting in San Francisco say high school teachers inspired them to pursue physics. Read More »
Single particles of light can be prepared in a quantum superposition of two different colors, an achievement that could prove useful for quantum information processing. Read More »
Experiments with ultracold magnetic atoms reveal liquid-like quantum droplets that are 20 times larger than previously observed droplets. Read More »
Calculations based on density-functional theory show that certain topological insulators can turn into conventional insulators at high temperature. Read More »
