Role of Disorder and Interactions on the Surface of Topological Superconductors

In this work we study the surface properties of topological systems, with a special focus on topological superconductors without inversion symmetry. These materials provide a rich playground for multiple topological phenomena, showing boundary modes with linear and (or) flat dispersion arising from complex nodal structures. A remarkable characteristic of topological phases is their robustness t...

Anomalous Aharonov-Bohm conductance oscillations from topological insulator surface states.

We study Aharonov-Bohm (AB) conductance oscillations arising from the surface states of a topological insulator nanowire, when a magnetic field is applied along its length. With strong surface disorder, these oscillations are predicted to have a component with anomalous period Φ(0)=hc/e, twice the conventional period. The conductance maxima are achieved at odd multiples of 1/2Φ(0), implying tha...

Interaction-induced criticality in Z(2) topological insulators.

We study interaction effects in topological insulators with strong spin-orbit coupling. We find that the interplay of nontrivial topology and Coulomb repulsion induces a novel critical state on the surface of a three-dimensional topological insulator. Remarkably, this interaction-induced criticality, characterized by a universal value of conductivity, emerges without any adjustable parameters. ...

Coulomb Gap in the Quantum Hall Insulator

We calculate numerically the spectrum of disordered electrons in the lowest Landau level at filling factor 1/5 using the self-consistent Hartree-Fock approximation for systems containing up to 400 flux quanta. Special attention is paid to the correct treatment of the q = 0 component of the Coulomb interaction. For sufficiently strong disorder, the system is an insulator at this filling factor. ...

A Single-Spin Switch

With magnetic tunnel junctions scaling down, new phenomena due to the correlated charge transport are anticipated. One relevant phenomenon is associated to the non-avoidable traps in the insulator. In particular, the Coulomb interaction leads to a strong repulsion on a trap, a Coulomb blockade, while the Pauli blockade results in spin-dependent correlations at the transport through quantum dots...
