Topological waves may help in understanding plasma systems

Nearly 50 years ago, Brown University physicist Michael Kosterlitz and his colleagues used the mathematics of topology—the study of how objects can be deformed by stretching or twisting but not tearing or breaking—to ...

The exceptional origin of EUV light in hot tin plasma

Extreme ultraviolet light (EUV light) does not naturally occur on Earth, but it can be produced. In nanolithography machines, EUV light is generated using an immensely hot tin plasma. Researchers at ARCNL, in close collaboration ...

Fossil fuel-free jet propulsion with air plasmas

Humans depend on fossil fuels as their primary energy source, especially in transportation. However, fossil fuels are both unsustainable and unsafe, serving as the largest source of greenhouse gas emissions and leading to ...
