Chiral filtering in graphene with coupled valleys
Pedro L. S. Lopes, A. H. Castro Neto, A. O. Caldeira
We analyze the problem of electronic transmission through different regions of a graphene sheet that are characterized by different types of connections between the Dirac points. T…
Effective response theory for zero energy Majorana bound states in three spatial dimensions
Pedro L. S. Lopes, Jeffrey C. Y. Teo, Shinsei Ryu
We propose a gravitational response theory for point defects (hedgehogs) binding Majorana zero modes in (3+1)-dimensional superconductors. Starting in 4+1 dimensions, where the poi…
Magnification of signatures of topological phase transition by quantum zero point motion
Pedro L. S. Lopes, Pouyan Ghaemi
In this letter we show that the zero-point motion of the vortex in superconducting doped topological insulators leads to significant changes in the electronic spectrum at the topol…
