Topological Insulators

Invited

Shoucheng Zhang Stanford University In this talk, I will discuss the quantized topological magneto-electric effect in topological insulators. In particular, I will present a number of proposals to detect this effect in low energy magneto-optical spectroscopy.

Topological Insulators

Invited

Gedik, Nuh MIT The three-dimensional topological insulator (TI) is a new quantum phase of matter that exhibits quantum-Hall-like properties, even in the absence of an external magnetic field. Charge carriers on the surface of a TI behave like a two-dimensional gas of massless helical Dirac fermions for which the spin is ideally locked perpendicular to the momentum. In this talk, I will...

Topological Insulators

Invited

Stefano Lupi Department of Physics University of Rome La Sapienza Topological Insulators (TI) are new quantum materials with an insulating-gap in the bulk of spin-orbit origin and metallic states at the surface. These states are chiral and show dissipation-less transport properties protected from disorder by the time-reversal symmetry. In addition to their fundamental properties, TI...
