Once fashioned, the crystals were loaded into this two-story device known as a scanning tunneling spectromicroscope to ensure that they matched theoretical specifications.

A Bangladeshi physicist of Princeton University led an international team to the discovery of an elusive massless particle theorised 85 years ago.
The particle could give rise to faster and more efficient electronics because of its unusual ability to be-have as matter and antimatter inside a crystal, quoting a new research a report was published on the university website.
“The physics of the Weyl fermion are so strange, there could be many things that arise from this particle that we’re just not capable of imagining now,” said corresponding author M Zahid Hasan, a Princeton professor of physics who led the research team.
Among two sons and a daughter, Hasan is the eldest of Rahmat Ali and Nadira Begum couple. His fa-ther is a lawyer and mother, housewife.
He did his SSC and HSC from Dhanmondi Government Boys High School and Dhaka College respec-tively. His bright results put him on the merit list, reports Bangla daily Prothom Alo.
Hasan studied in The University of Texas at Austin, United States, got his PhD from Stanford University. After completing his degree there he joined Princeton University as a lecturer. At present he is a Professor of Physics with a specific interest on the field of Quantum Condensed Matter Physics at the university, the Bangla daily said.
The researchers report in the journal Science July 16 the first observation of Weyl fermions, which, if applied to next-generation electronics, could allow for a nearly free and efficient flow of electricity in electronics, and thus greater power, especially for computers, the researchers suggest.
