Physicists have controlled the quantum state of a crystal defect artificially created in a material using a resonant laser. This approach has enabled them to generate indistinguishable photons, the…
Flips describe the transition of a random walker from one edge of the territory he has already visited to the other. Despite their apparent complexity for walkers with memory, they obey a universal…
This study shows that quasicrystals, although they do not have a repeating pattern, inherit the topological properties of the quantum Hall effect. Using the Fibonacci–Hall model, the researcher…
Physicists have succeeded in observing diffraction patterns of unprecedented quality by passing fast hydrogen atoms through a sheet of graphene just one atom thick, an experimental and theoretical…
