In a new study published in Nature Physics, researchers have demonstrated that quantum light, particularly bright squeezed vacuum (BSV), can drive strong-field photoemission at metal needle tips.

Using observations from a NASA suborbital rocket, an international team of scientists, for the first time, has successfully measured a planet-wide electric field thought to be as fundamental to Earth ...

Explore the electric field along the axis of a charged rod in this in-depth physics tutorial! ⚡📚 Learn how to calculate and visualize the electric field created by a uniformly charged rod and ...

As the Parker Solar Probe ventures closer to the sun, we are learning new things about our home star. In a new study, physicists led by the University of Iowa report the first definitive measurements ...

A new quantum sensing approach could dramatically improve how scientists measure low-frequency electric fields, a task that has long been limited by bulky setups and blurry resolution. Instead of ...

For the first time, scientists have measured a long-sought global electric field in the Earth’s atmosphere. This field, called the ambipolar electric field, was predicted to exist decades ago but ...
