One-dimensional helical liquids can appear at boundaries of certain condensed matter
systems. Two prime examples are the edge of a quantum spin Hall insulator and the hinge …

We consider a normal lead coupled to a Majorana bound state. We show that the spin-
resolved current correlations exhibit unique features which distinguish Majorana bound …

We study the thermoelectric response of a device containing a pair of helical edge states
contacted at the same temperature T and chemical potential μ and connected to an external …

We analyze the spatial correlation structure of the spin density of an electron gas in the
vicinity of an antiferromagnetically coupled Kondo impurity. Our analysis extends to the …

In this work, using the finite-U slave boson mean-field approximation to solve the single-
impurity Anderson model, the authors apply two different strategies to study the Kondo …

The edge channels of two-dimensional topological systems are protected from elastic
reflection and are noiseless at low temperature. Yet, noise and cross correlations can be …

Using the natural orbitals renormalization group, we studied the problem of a localized spin-
1 2 impurity coupled to two helical liquids via the Kondo interaction in a quantum spin Hall …

We study the two-channel Kondo problem in the context of two interacting helical liquids
coupled to a spin-1 2 magnetic impurity. We show that the interactions between the two …

We study the transport mechanisms taking place in a quantum spin Hall bar with an
embedded quantum dot, where electrons localize and experience Coulomb interaction U as …

We investigate electron transport through an antidot embedded in a narrow strip of a two-
dimensional topological insulator. We focus on the most generic and experimentally relevant …
