PREDICTED PHENOMENA. “Temporal condensed matter phenomena that have been predicted to date include Mott insulator phases in the time dimension: Anderson localization and many-body localization in the time dimension; topologically protected edge states in time; quasi-crystal structures in time; two-dimensional time lattices supporting a Möbius strip geometry and flat-band physics; and time-space crystals exhibiting a six-dimensional quantum Hall effect.” https://lnkd.in/e5UXiem5 View in LinkedIn

FRAGMENT FROM NATURE is a Mind warp, touching the extraordinary world of condensed matter physics, higher dimensions, and broken symmetry in time. The ideas explored, including quite magical mathematics, are straight out of Alice in Wonderland. There are, it seems, few limits to creative thinking. https://lnkd.in/e5UXiem5 View in LinkedIn

DURABLE. “Such discrete time crystals are robust against external perturbations and quantum fluctuations and live for extremely long times.” https://lnkd.in/e5UXiem5 View in LinkedIn

NEW POSSIBILITIES. “This allows the creation of big discrete time crystals possessing a large number of temporal lattice sites, which are suitable for realizing a broad range of condensed matter phenomena in the time dimension.” https://lnkd.in/e5UXiem5 View in LinkedIn

LONG PERIODS. “Such a system has been shown to exhibit dramatic breaking of discrete time-translation symmetry in which the bouncing atoms can evolve with periods up to about 100 times longer than the period of the drive.” https://lnkd.in/e5UXiem5 View in LinkedIn

SPREADING UNCERTAINTY. “Instead, the universe-scale factor a(t) must experience quantum fluctuations, especially since there is no reason to expect that the quantum state of the universe within the scope of the quantum Friedmann model will always be a scale factor eigenstate.” https://www.mdpi.com/2218-1997/7/6/164/htm View in LinkedIn

UNCERTAINTY PRINCIPLE. “Similar to quantum mechanics, in the semi-classical quantum gravity picture, we should expect a(t) not to be well-defined.” (a(t) = the universe-scale factor). https://www.mdpi.com/2218-1997/7/6/164/htm View in LinkedIn

RIDDLED WITH FIELDS. “Like any other object, the center of mass of a system experiences quantum fluctuations.” https://www.mdpi.com/2218-1997/7/6/164/htm View in LinkedIn

HEISENBERG. “In the quantum mechanical picture, the center of mass motion obeys the uncertainty principle, and thus is not well-defined anymore.” https://www.mdpi.com/2218-1997/7/6/164/htm View in LinkedIn
