Physicists have created a system of two connected time crystals, which are strange quantum systems that are stuck in an endless loop to which the normal laws of thermodynamics do not apply. By connecting two time crystals together, the physicists … Read more
I woke up this morning to find out that a new Higgs particle which could explain dark matter has been discovered, in a table-top experiment at Boston College. For some of the news stories about this, see here and here. … Read more
Classical thermodynamics has only a handful of laws, of which the most fundamental are the first and second. The first says that energy is always conserved; the second law says that heat always flows from hot to cold. More commonly … Read more

Physicists in the MIT-Harvard Center for Ultracold Atoms developed a new approach to control the outcome of chemical reactions, using minute changes in a magnetic field to make subtle changes to the quantum mechanical wavefunction of the colliding particles during … Read more
The FASER particle detector that received CERN approval to be installed at the Large Hadron Collider in 2019 has recently been augmented with an instrument to detect neutrinos. The UCI-led FASER team used a smaller detector of the same type … Read more

Like a child learning math, scientists developing quantum computers—dream machines that could crack problems that would overwhelm any supercomputer—are learning to spot and correct their mistakes. In the latest step, a team has demonstrated a way to detect errors in … Read more
In 1934, Eugene Wigner, a pioneer of quantum mechanics, theorized a strange kind of matter — a crystal made from electrons. The idea was simple; proving it wasn’t. Physicists tried many tricks over eight decades to nudge electrons into forming … Read more
There are certain rules that even the most extreme objects in the universe must obey. A central law for black holes predicts that the area of their event horizons — the boundary beyond which nothing can ever escape — should … Read more
