From time quasicrystal to superfluid time crystal
https://www.researchgate.net/publication/321936517_From_time_quasicrystal_to_superfluid_time_crystal We report experimental realization of a quantum time quasicrystal, and its transformation to a quantum time crystal. We study magnon BECs, associated with coherent spin precession, created in a flexible trap in superfluid $^3$He-B. Under a periodic RF drive, the coherent spin precession is stabilized at a frequency smaller than that of the drive, […]
