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

A simplification of superfluidity
“Once people tell me what symmetry the system starts with and what symmetry it ends up with, and whether the broken symmetries can be interchanged, I can work out exactly how many bosons there are and if that leads to … Continue reading
