a: time crystal ~
b: a spatial crystal that adds symmetry
What:
"A time crystal is like a spatial crystal that adds symmetry in the fourth dimension, in time as well as in space. Something that's symmetric in time is sort of like a clock: there's a repeating pattern of motion through time, and it's this pattern of motion that's analogous to the repeating pattern of atoms in space."
