  • Band Gap Size Dependence of Topological Insulator Bi2Te3 Nanotube 
    BEJENARI, Igor; KANTSER, Valeriu (Technical University of Moldova, 2011)
    We study the electronic structure of a cylindrical nanotube made of a topological insulator Bi2Te3. The calculation was made in the framework of the kp theory near the Γ point of the surface Brilloiun zone. A band gap size ...
  • Topological materials and topological quantum computing 
    KANTSER, V. (Technical University of Moldova, 2011)
    A paradigm to build a quantum computer based on topological invariants is highlighted. The identities in the ensemble of knots, links and braids originally discovered in relation to topological quantum field theory are ...
