Periodic Reporting for period 2 - BALLISTOP (Revealing 1D ballistic charge and spin currents in second order topological insulators)

One of the greatest recent achievement in Condensed matter physics is the discovery of a new class of materials, Topological Insulators (TI), whose bulk is insulating, while the edges conduct current in a quasi-ideal way. In particular, the 1D edges of 2DTI realize the Quantum...
