Floquet-Bloch State: Persuading Light To Mix It Up With Matter

Researchers have made a step toward the creation of materials that can be 'tuned' just by shining a light on them- they have succeeded in producing and measuring a coupling of photons and electrons on the surface of an unusual type of material c ...

Sorites Paradox: Many-Body Systems And How Few Particles Become A 'Heap'

At some point the exact number of particles in a group becomes irrelevant. But does when a collection of elements forms a "heap"? In recent experiments using ultracold atoms, Heidelberg physicists succeeded in observing the transition to a many-b ...

1988- The Second Discovery Of The Top Quark

These days I am trying to reconstruct some stories from my old experiment, CDF. The CDF experiment was conceived in 1979 and constructed in the early eighties at the Fermi laboratories in Batavia, near Chicago. CDF took the first proton-antiproton collisi ...
