Spin connection and boundary states in a topological insulator
Spin connection boundary states topological insulator
2010/12/24
We study the surface resistivity of a three-dimensional topological insulator when the boundaries exhibit a non trivial curvature. We obtain an analytical solution for a spherical topological insulato...
Inducing topological order in a honeycomb lattice
Inducing topological order honeycomb lattice
2010/11/25
We explore the possibility of inducing a topological insulator phase in a honeycomb lattice using a metallic gate. We start with a lattice model which does not include spin-orbit interaction. A metall...
Topological approach toward quantum codes with realistic physical constraints
Topological approach toward quantum codes realistic physical constraints
2010/11/5
The following open problems, which concern a fundamental limit on coding properties of quantum codes with realistic physical constraints, are analyzed and partially answered here: (a) the upper bound ...
Topological Mass Generation and Duality Transformations in Diverse Dimensions
Topological Mass Generation Duality Transformations Diverse Dimensions
2010/10/18
In this seminar we shall discuss the issue of duality transformation in the context of f topological mass generation in diverse dimensions. Particular emphasis will be given to the mass generation mec...
