In the quantum material tantalum arsenide (TaAs), electrons form vortices in momentum space. Momentum space is a physics concept used to analyze how electrons behave in solids.

A team of researchers from Würzburg has for the first time experimentally demonstrated a #quantum tornado. Electrons form vortices in the momentum space of the quantum semi-metal tantalum arsenide go.uniwue.de/tornado #PhysicalReview 📷 think-design | Jochen Thamm

#JulianSeymourSchwinger, one of the creators of quantum electrodynamics
During his high school studies, Schwinger started reading #PhysicalReview papers by authors such as #PaulDirac in the library of the City College of New York. At the age of 16, he published his first physics paper.
