Weyl metallic state induced by helical magnetic order
Henrik Moodysson Rønnow, Jan Hugo Dil, Ivica Zivkovic, Jian Rui Soh, Xupeng Yang
In the rapidly expanding field of topological materials there is growing interest in systems whose topological electronic band features can be induced or controlled by magnetism. Magnetic Weyl semimetals, which contain linear band crossings near the Fermi ...
Berlin2024Type-I antiferromagnetic Weyl semimetal InMnTi2
Nicola Marzari, Davide Grassano, Luca Binci
Topological materials have been a main focus of studies in the past decade due to their protected properties that can be exploited for the fabrication of new devices. Among them, Weyl semimetals are a class of topological semimetals with nontrivial linear ...
College Pk2024Machine-learning the electronic density of states: electronic properties without quantum mechanics
The electronic density of states (DOS) quantifies the distribution of the energy levels that can be occupied by electrons in a quasiparticle picture and is central to modern electronic structure theory. It also underpins the computation and interpretation ...
EPFL2023Complementary screening for quantum spin Hall insulators in two-dimensional exfoliable materials
Nicola Marzari, Davide Campi, Antimo Marrazzo, Davide Grassano
Quantum spin Hall insulators are a class of topological materials that has been extensively studied during the past decade. One of their distinctive features is the presence of a finite band gap in the bulk and gapless, topologically protected edge states ...
College Pk2023Unconventional Flat Chern Bands and 2e Charges in Skyrmionic Moire Superlattices
The interplay of topological characteristics in real space and reciprocal space can lead to the emergence of unconventional topological phases. In this Letter, we implement a novel mechanism for generating higher-Chern flat bands on the basis of twisted bi ...
AMER CHEMICAL SOC2023Dissipative boundary state preparation
We devise a generic and experimentally accessible recipe to prepare boundary states of topological or non topological quantum systems through an interplay between coherent Hamiltonian dynamics and local dissipation. Intuitively, our recipe harnesses the sp ...
College Pk2023Phase of Topological Lattice with Leaky Guided Mode Resonance
Kirsten Emilie Moselund, Chang Won Lee
Topological nature in different areas of physics and electronics has often been characterized and controlled through topological invariants depending on the global properties of the material. The validity of bulk-edge correspondence and symmetry-related to ...
Basel2023Phonon Self-Energy Corrections: To Screen, or Not to Screen
First-principles calculations of phonons are often based on the adiabatic approximation and on Brillouinzone samplings that might not always be sufficient to capture the subtleties of Kohn anomalies. These shortcomings can be addressed through corrections ...
College Pk2023Anisotropic and nonlinear transport in microstructured 3D topological semimetals
Topological semimetals are frequently discussed as materials platforms for future electronics that exploit the remarkable properties of their quasiparticles. These ideas are mostly based on dispersion relations that mimic relativistic particles, such as We ...
EPFL2022Addressing shape and extent of Weyl cones in TaAs by Landau level spectroscopy
TaAs is a prime example of a topological semimetal with two types of Weyl nodes, W-1 and W-2, whose bulk signatures have proven elusive. We apply Landau level spectroscopy to crystals with multiple facets and identify-among other low-energy excitations bet ...
