Crystal chain: Artist’s impression of the discrete time crystal made at QuTech. A chain of connected spins is locked in a phase in which they periodically invert their state. (Courtesy: Joe Randall ...

In a new study published in Nature Physics, researchers achieved the first experimental observation of a time rondeau crystal ...

Split a mile in half, you get half a mile. Split the half mile, you get a quarter, and on and on, until you’ve carved out a length far smaller than the diameter of an atom. Can this slicing continue ...

Can discretely sampled financial data help us decide which continuous-time models are sensible? Diffusion processes are characterized by the continuity of their sample paths. This cannot be verified ...
