Experimental and theoretical physicists from the Würzburg Institute for Topological Insulators observed a re-entrant quantum Hall effect in a mercury telluride device and identify it as a signatur ...
The theoretical discovery and experimental realisation of topological insulators, a new state of matter, has brought enormous research interest in the field of condensed matter physics. The novel and fascinating phenomenon in topological insulators (TIs) is the existence of gapless surface states (or edge states) while the bulk interior has an energy gap. These states are intriguing because they enable the transport of charges with no backscattering, which means less heat generation than ordinary conductors. The unique transport in TIs arises because of the spin-momentum locking of the surface...
Physicist Xue Qikun has become the first Chinese scientist to receive the U.S.’ prestigious Oliver E. Buckley Condensed Matter Physics Prize since its inception 70 years ago. The prestigious award: Xue and Harvard University’s Ashvin Vishwanath was jointly awarded a $20,000 cash prize on Tuesday for their groundbreaking work in the field of topological insulators. Xue, who is a professor at Tsinghua University in Beijing, has been at the forefront of topological insulator research for over a decade and has previously received numerous accolades for his work.
Researchers from the University of Rostock and Technion Haifa have created the first three-dimensional topological insulator for light. A judiciously placed screw dislocation allows optical signal ...
