CERN Physicists Measure Elliptic Flow of Bottomonium Particles

Physicists in the ALICE (A Large Ion Collider Experiment) Collaboration at CERN have announced the first measurements of an elliptic-shaped flow of upsilons, bottomonium particles consisting of a bottom quark and its antiquark. One of the first collisions of lead ions recorded by the ALICE detector. Image credit: ALICE Collaboration …

Scientists Capture Photographic Proof of Quantum Entanglement

  Humans tend to think they have a pretty good handle on how the physical world operates, but things get unspeakably weird at the small scale. Particles aren’t always particles, and sometimes those particles (or waves) behave in bizarre, counterintuitive ways. One of the strangest features of physics is quantum …

Physicists Teleport Quantum Information inside Diamond

A team of physicists at the Yokohama National University, Japan, has successfully demonstrated quantum teleportation — the remote exchange of quantum states — in a diamond. The lattice structure of diamond contains a nitrogen-vacancy center with surrounding carbon nuclear spins; the carbon isotope 13C (green) is first entangled with an …

Physicists Capture Atomic Motion in 4D

A process called nucleation plays a critical role in many physical and biological phenomena that range from crystallization, melting and evaporation to the formation of clouds and the initiation of neurodegenerative diseases. However, nucleation is a challenging process to study experimentally, especially in its early stages, when several atoms or …

Physicists Use MRI to Scan Individual Atoms

A team of experimental physicists from the Institute for Basic Science, the Ewha Womans University and the IBM Almaden Research Center has performed the world’s smallest magnetic resonance imaging (MRI) to visualize the magnetic field of single atoms. The results are published in the journal Nature Physics. Single magnetic atoms …

Researchers May Finally Have Created Metallic Hydrogen

  Scientists have been trying to produce metallic hydrogen for decades, but no one has managed to show incontrovertible evidence of success yet. A team of researchers at France’s Atomic Energy Commission is the latest to claim success via a paper posted to the online arXiv server. The scientists used …

Physicists Observe Exotic Quantum States in Double-Layer Graphene

An international team of physicists from the United States and Japan has demonstrated a series of fractional quantum Hall effect states that arise in double-layer stacks of graphene. The team’s paper was published in the journal Nature Physics. A new type quasiparticle discovered in graphene double-layer structure. This so-called composite …
