Spectral asymmetry induces a re-entrant quantum Hall effect in a topological insulator
Li-Xian Wang, Wouter Beugeling, Fabian Schmitt +5
The band inversion of topological materials in three spatial dimensions is intimately connected to the parity anomaly of two-dimensional massless Dirac fermions. At finite magnetic…
Evolution of the surface states of the Luttinger semimetal under strain and inversion-symmetry breaking: Dirac, line-node, and Weyl semimetals
Maxim Kharitonov, Julian-Benedikt Mayer, Ewelina M. Hankiewicz
The Luttinger model of a quadratic-node semimetal for electrons with the angular momentum under cubic symmetry is the parent, highest-symmetry low-energy model for a va…
Intrinsic emergence of Majorana modes in Luttinger j=3/2 systems
Julian Benedikt Mayer, Miguel A. Sierra, Ewelina M. Hankiewicz
We analyze theoretically two different setups for s-wave superconductivity (SC) proximitized particles in Luttinger materials that are able to host Majorana bound states (M…
Counterpropagating topological and quantum Hall edge channels
Saquib Shamim, Pragya Shekhar, Wouter Beugeling +7
The survival of the quantum spin Hall edge channels in presence of an external magnetic field has been a subject of experimental and theoretical research. The inversion of Landau l…
Interplay of Dirac nodes and Volkov-Pankratov surface states in compressively strained HgTe
David M. Mahler, Julian-Benedikt Mayer, Philipp Leubner +8
Preceded by the discovery of topological insulators, Dirac and Weyl semimetals have become a pivotal direction of research in contemporary condensed matter physics. While easily ac…
Universality and stability of the edge states of chiral-symmetric topological semimetals and surface states of the Luttinger semimetal
Maxim Kharitonov, Julian-Benedikt Mayer, Ewelina M. Hankiewicz
We theoretically demonstrate that the chiral structure of the nodes of nodal semimetals is responsible for the existence and universal local properties of the edge states in the vi…
