Intrinsic Magnetic Topological Insulator

Authors: George Rajna

The team that includes DIPC researchers Mikhail Otrokov (CFM Ikerbasque Research Fellow), Evgueni Chulkov (UPV/EHU, Euskadi Research Prize 2019), María Blanco Rey (UPV/EHU) and Pedro M. Echenique (UPV/EHU, DIPC President), has predicted theoretically the first intrinsic magnetic topological insulator, with chemical formula MnBi2Te4. [35] Since their discovery in 2006, topological insulators have been widely discussed as a promising avenue for energy efficient electronics. [34] For the first time, a group of researchers from Universidad Complutense de Madrid, IBM, ETH Zurich, MIT and Harvard University have observed topological phases of matter of quantum states under the action of temperature or certain types of experimental imperfections. [33] With their insensitivity to decoherence, Majorana particles could become stable building blocks of quantum computers. [32] A team of researchers at the University of Maryland has found a new way to route photons at the micrometer scale without scattering by building a topological quantum optics interface. [31] Researchers at the University of Bristol's Quantum Engineering Technology Labs have demonstrated a new type of silicon chip that can help building and testing quantum computers and could find their way into your mobile phone to secure information. [30] Theoretical physicists propose to use negative interference to control heat flow in quantum devices. [29] Particle physicists are studying ways to harness the power of the quantum realm to further their research. [28]
