If two particles are produced close to each other and with similar momenta and direction, the pair can be subject to quantum statistics, Coulomb force and strong interaction. If one of the pair is a ...

Most ordinary matter is held together by an invisible subatomic glue known as the strong nuclear force — one of the four fundamental forces in nature, along with gravity, electromagnetism, and the ...

New research conducted by nuclear physicists is using a method that connects theories of gravitation to interactions among the smallest particles of matter. The result is insight into the strong force ...

Force spectroscopy relies on the precise measurement of forces acting on a probe as it interacts with a sample. The key principles of force spectroscopy include: AFM-based force spectroscopy is the ...

The strongest force in the universe is called, aptly, the strong force. We never get to witness its fearsome power because it works only across subatomic distances, where it binds quarks together ...

The power of gravity is writ large across our visible universe. It can be seen in the lock step of moons as they circle planets; in wandering comets pulled off-course by massive stars; and in the ...
