Physicists Experimentally Observe Decay of Quantum Monopole

An international team of physicists from Finland and the United States has made the first experimental observations of the dynamics of isolated monopoles in quantum matter. The results are published in the journal Physical Review X. This is an artistic view of the decay of a quantum-mechanical monopole into a …

Physicists Directly Observe Hydrogen Bonds in Single Molecule

For the first time, physicists have succeeded in observing and studying in detail the hydrogen bonds in a single molecule. Quantitative measurements of the C═O***H–C bond: (A) schematic drawing of the hydrogen bonding measurement on trifluorantheno[3.3.3]propellane with a CO-functionalized tip; right shows the AFM image. Scale bar – 300 pm; …

Is There a Resting Frame in Universe?

Physics is sometimes closer to philosophy when it comes to understanding the Universe. Dr. Donald Chang, a physicist at the Hong Kong University of Science and Technology, attempts to elucidate whether the Universe has a resting frame. An experiment proposed by Dr. Donald Chang aims at resolving divergence between special …
