OUT OF THE BOX. “In 2012 Frank Wilczek speculated whether crystalline structures in space could be extended to the fourth dimension – time?” https://lnkd.in/e5UXiem5 View in LinkedIn

QUANTUM TIME CRYSTALS. “To create such a ‘quantum time crystal’, he considered the possibility of spontaneous breaking of continuous time-translation symmetry in the ground state of a many-body system, in analogy with the formation of an ordinary crystal in space.” https://lnkd.in/e5UXiem5 View in LinkedIn

TOO FAR OUT. “While a classical particle can perform periodic motion even if its energy is the lowest possible and a classical time crystal can form, the quantum time crystal proposed by Wilczek turned out not to be feasible.” https://lnkd.in/e5UXiem5 View in LinkedIn

IMPETUS. “However, his idea inspired further proposals in time-independent and time-dependent quantum systems.” https://lnkd.in/e5UXiem5 View in LinkedIn

BREAKING SYMMETRY. “In particular, it was shown that a periodically driven many-body system can spontaneously break discrete time-translation symmetry and self-reorganize its motion so that it evolves with a period longer than the drive.” https://lnkd.in/e5UXiem5 View in LinkedIn

OPTIONS. “To create such a ‘discrete time crystal’, a range of experimental platforms have been proposed, including a periodically driven Bose-Einstein condensate, driven spin-based systems, and driven open dissipative systems.” https://lnkd.in/e5UXiem5 View in LinkedIn

CONDENSED MATTER PHYSICS. “We consider the case of a Bose-Einstein condensate (BEC) of ultracold atoms bouncing resonantly on an oscillating atom mirror.” https://lnkd.in/e5UXiem5 View in LinkedIn
