A microscope that catches the slightest hints of heat
A superconducting transition-edge sensor (TES) is a device well-known for its extreme sensitivity to photons, the particles of light — so much so that they can count photons one by one. They also have very little noise, which makes their … Continue reading

Quasiparticles do the twist
Physics often involves hidden surprises in how matter behaves at the smallest scales. A fundamental property in physics is angular momentum, which describes how things spin or rotate, from planets all the way down to particles. Angular momentum is involved … Continue reading

Looking for ghost particles in a frustrated world
In some of the many types of objects and events involving electrons, it is helpful to think that these particles are made up of three smaller particles, called spinons, holons and orbitons. Physicists call these supposedly imaginary particles quasiparticles. By … Continue reading

A tale of vortices, skyrmions, paths and shapes
There are many types of superconductors. Some of them can be explained by an early theory of superconductivity called Bardeen-Cooper-Schrieffer (BCS) theory. In these materials, vibrations in the atomic lattice force the electrons in the material to overcome their mutual … Continue reading

Physicists produce video of time crystal in action 😱
Have you heard of time crystals? A crystal is any object whose atoms are arranged in a fixed pattern in space, with the pattern repeating itself. So what we typically know to be crystals are really space crystals. We didn’t … Continue reading
