THE PLAN. “Although time is a single degree of freedom, crystalline structures in time with the properties of 2D (or 3D) condensed matter systems can be created by a BEC bouncing resonantly between two (or three) oscillating atom mirrors.” (BEC = Bose-Einstein condensate). https://lnkd.in/e5UXiem5 View in LinkedIn

OFF-DIAGONAL RESPONSES. “As the multipole classification scheme can be generalized to systems characterized by a specific point group symmetry, multipole theory is becoming used for the classification of off-diagonal response phenomena, such as the electric-magnetic effect and the anomalous Hall effect in antiferromagnets.” https://journals.jps.jp/doi/full/10.7566/JPSJ.87.041008 View in LinkedIn

OPEN AVENUE. “If a resonantly driven many-body system experiences temporal disorder, the many-body localization phenomenon in a time crystalline structure can be investigated.” https://lnkd.in/e5UXiem5 View in LinkedIn

PUSHING THE ENVELOPE. “We have seen that a resonantly driven single particle can behave in the time domain like an electron moving in a space crystal. One may raise the question if many-body condensed matter phenomena can be observed in the time dimension too?” https://lnkd.in/e5UXiem5 View in LinkedIn

TEASER. “What do the pyramids of Giza and Da Vinci’s Mona Lisa have in common with Twitter and Pepsi?” https://lnkd.in/ejjhttcs View in LinkedIn

RANGE OF FORMS. “We have seen that different crystalline structures can be realized in the time domain by means of resonant driving of a periodically moving particle.” https://lnkd.in/e5UXiem5 View in LinkedIn

SO ENDS this second and last weekend on time crystals, a topic so far our that it is hard to even imagine. But it is clear that we have only just started scratching the surface of the places where numbers fail, physics needs new laws, and everything goes pear-shaped; these include black holes, where time is speculated to cease, antimatter stars, strange matter stars, magnetars, and other extreme astrophysical places. https://lnkd.in/e5UXiem5 View in LinkedIn

NEW VISTAS. “The application of big discrete time crystals to condensed matter physics in the time dimension has opened up a rich new area of research ready to be exploited experimentally.” https://lnkd.in/e5UXiem5 View in LinkedIn

THEORY. “Condensed matter phenomena in the time dimension that have been predicted to date include Anderson and many-body localization due to temporal disorder, topological time crystals, quasi-crystal structures in time, and Mott insulator phases in time.” https://lnkd.in/e5UXiem5 View in LinkedIn
