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.

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 ...

Electric fields can feel abstract, but interactive simulations make them tangible. From placing charges to mapping equipotential lines, these tools bring invisible forces to life. Whether you’re a ...

The field of electromedicine is witnessing significant advances with the advent of impulse electrical technologies, including nanosecond pulsed bioelectrics ...

Coulomb’s law explains how charged objects interact, with the force depending on the magnitudes of the charges and the square of the distance between them. Like charges repel and opposite charges ...

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 ...
