A research team at Penn State has reported a significant violation of Kirchhoff’s law of thermal radiation, a principle that has been a foundation of thermal physics for 165 years. Their findings ...

Left: Initial temperature and density setup, which mirrors conditions of the stable and isobaric burning process. Middle: the ion scattering trajectories for large or small angles, and the boundaries ...

In many quantum materials—materials with unusual electrical and magnetic properties driven by quantum mechanical effects—electrons can organize themselves into Landau levels. Landau levels are ...
