M. Zahid Hasan has discovered the Weyl fermions

85 years ago German physicist and mathematician Herman Weyl, first mooted in 1929 who theorized that massless fermions able to carry an electric charge faster. An international team Princeton University researchers led by M. Zahid Hasan has discovered the Weyl fermions which applied to next generation electronics more efficient.


An international science journal in July 16, 2015, the researchers report that Weyl fermions allow for a nearly free and efficient flow of electricity in electronics, and thus greater power, especially for smart phones and computers.


Bangladeshi scientist Zahid Hasan explained how the Weyl fermions characteristics that could make its discovery a boon for future electronics, including the development of the highly prized field of efficient quantum computing.


The researchers of Princeton University also found that Weyl fermions can be used to create massless electrons that move very quickly with no backscattering, wherein electrons are lost when they collide with an obstruction, M. Zahid Hasan said.


“The nature of this research and how it emerged is really different and more exciting than most of other work we have done before,” said Su-Yang Xu, a postdoctoral research associate at Princeton. “Usually, theorists tell us that some compound might show some new or interesting properties, then we as experimentalists grow that sample and perform experiments to test the prediction. In this case, we came up with the theoretical prediction ourselves and then performed the experiments. This makes the final success even more exciting and satisfying than before.”


Professor Zahid Hasan said, “It’s like they have their own GPS and steer themselves without scattering. They will move and move only in one direction since they are either right-handed or left-handed and never come to an end because they just tunnel through. These are very fast electrons that behave like unidirectional light beams and can be used for new types of quantum computing.”


Also said physicist Zahid Hasan said, “People figured that although Weyl’s theory was not applicable to relativity or neutrinos, it is the most basic form of fermion and had all other kinds of weird and beautiful properties that could be useful. After more than 80 years, we found that this fermion was already there, waiting. It is the most basic building block of all electrons. It is exciting that we could finally make it come out following Weyl’s 1929 theoretical recipe.”
