The findings are presented in two new joint research papers, one describing theory ( "Topological insulator laser: Theory" ) and the other experiments ( "Topological insulator laser: Experiments" ), published online today by the Ferromagnetic topological insulators (TIs) have promise for applications in spintronics, metrology, and quantum computing. However, TI materials are fragile and often incompatible with nanofabrication techniques. Here, we demonstrate persistent, micron-scale optical control of both magnetization and chemical potential in Cr-(Bi,Sb)2Te3 grown on SrTiO3.

Creating a band gap. The different patterns of the two photonic crystals gave rise to a one-way, robust photonic edge state, much like the electronic edge states in a topological insulator. 2020-06-02 · Topological insulators represent a recently discovered class of solids, which are insulating in their bulk but exhibit special scattering-resistant conducting states on their surfaces, known as topological edge states. 1 1.
