WebNow time crystals have been previously theoretically predicted to exist "Classical Time Crystals" and "Quantum Time Crystals", representing an out-of-equilibrium form of matter, in contrast to the commonly well known equilibrium forms of matter (solid, gas, liquids, liquid crystals...). So it is really great to see such works emerging and the ... In condensed matter physics, a time crystal is a quantum system of particles whose lowest-energy state is one in which the particles are in repetitive motion. The system cannot lose energy to the environment and come to rest because it is already in its quantum ground state. Because of this, the motion of the particles does not really represent kinetic energy like other motion; it has "moti…
