Dirac

Indispensable Research for Future Information and Computing Technologies Conducted by U.S. Department of Energy

A team led by the Department of Energy’s Oak Ridge National Laboratory has found a rare quantum material in which electrons move in coordinated ways, essentially “dancing.” Straining the material creates an electronic band structure that sets the stage for exotic, more tightly correlated behavior – akin to tangoing – among Dirac electrons, which are especially mobile electric charge carriers that may someday enable faster transistors. The results are published in the journal Science Advances.

Making Quantum Devices With Higher-Dimensional Topological States

Linked Weyl surfaces, a novel type of topological phase that exists in five-dimensional space, were experimentally observed for the first time by a team led by Professor Shuang ZHANG from the Department of Physics at The University of Hong Kong(HKU). The work provides a unique platform for exploring various topological phases, the transition between them, and the corresponding boundary effects in five dimensions. The research paper was recently published in the renowned journal Science.
