Abstract In one-dimensional (1D) systems, electronic interactions lead to a breakdown of
Fermi liquid theory and the formation of a Tomonaga-Luttinger Liquid (TLL). The strength of …

We report on the observation of a helical Luttinger liquid in the edge of an InAs/GaSb
quantum spin Hall insulator, which shows characteristic suppression of conductance at low …

The simplest possible structural transition that an electronic system can undergo is Wigner
crystallization. The aim of this short review is to discuss the main aspects of three recent …

Topology in condensed matter physics manifests itself in the emergence of edge or surface
states protected by underlying symmetries. We review two-dimensional topological …

Topological superconductors give rise to unconventional superconductivity, which is mainly
characterized by the symmetry of the superconducting pairing amplitude. However, since the …

We demonstrate that a combination of disorder and interactions in a two-dimensional bulk
topological insulator can generically drive its helical edge insulating. We establish this within …

We study the Wigner crystallization on partially filled topological flat bands of kagome,
honeycomb and checkerboard lattices. We identify the Wigner crystals (WCs) by analyzing …

We propose a novel realization for a topologically superconducting phase hosting Majorana
zero modes on the basis of quantum spin Hall systems. Remarkably, our proposal is …

The chiral anomaly is based on a nonconserved chiral charge and can happen in Dirac
fermion systems under the influence of external electromagnetic fields. In this case, the …

Thermal effects on the total charge density are studied for a one-dimensional correlated
quantum dot by means of the path integral Monte Carlo method. The competition between …
