Physicists Create Unexpected New Form of Plutonium

Physicists using the European Synchrotron Radiation Facility have created a new compound of plutonium (Pu) with an unexpected, pentavalent oxidation state — Pu (V). The new compound is solid and stable, and may represent a transient phase in radioactive waste repositories. A plutonium dioxide nanoparticle. Image credit: Kristina Kvashnina. One …

Non-Abelian Gauge Fields Directly Observed for First Time

After decades of unsuccessful attempts, physicists have directly observed an exotic physical phenomenon called the non-Abelian Aharonov-Bohm effect. The findings could lead to realizations of what are known as topological phases, and eventually to advances toward fault-tolerant quantum computers. To confirm the presence of non-Abelian gauge fields, Yang et al …

Theoretical Physicists Describe New Kind of Quantum Time Order

One of the fundamental principles of quantum mechanics is quantum superposition, in which a particle exists in two or more states simultaneously. In a paper published in the journal Nature Communications, University of Queensland physicist Magdalena Zych and colleagues show that particles are not the only objects that can exist …
