A group of scientists from the US and Prof. Krzysztof Sacha from the Jagiellonian University have just presented a breakthrough in their work on time crystals, the journal Nature Communications reported. Temporal crystals are structures that have only been studied for the past 10 years, which, like crystals in space, show regularity, but in time. It is likely that various types of components, such as superconductors or transistors, can be reproduced in them.
