The researchers used mathematical models based on the Dirac-Weyl equation to simulate how an electron in a graphene sheet would behave under external magnetic fields.

With the advances in technology our knowledge of subatomic particles and how they behave has improved considerably. But much is yet to be discovered in the subnuclear realm. Scientists from the Indian Institute of Science Bangalore, Horia Hulubei National Institute for Physics and Nuclear Engineering, Romania, and Physical Research Laboratory, Ahmedabad have developed a theoretical framework to measure the diameter of a Pion.
