Theory of Glide Symmetry Protected Helical Edge States in WTe Monolayer

Maciej Bieniek, Jukka I. Väyrynen, Gang Li +2

Helical edge states in quantum spin Hall (QSH) materials are central building blocks of topological matter design and engineering. Despite their principal topological protection ag…

Lifting topological protection in a quantum spin Hall insulator by edge coupling

Raul Stühler, André Kowalewski, Felix Reis +7

The scientific interest in two-dimensional topological insulators (2D TIs) is currently shifting from a more fundamental perspective to the exploration and design of novel function…

From high- to low-: Multi-orbital effects in transition metal oxides

Michael Klett, Tilman Schwemmer, Sebastian Wolf +8

Despite the structural resemblance of certain cuprate and nickelate parent compounds there is a striking spread of among such transition metal oxide superconductors. We adopt…

Competition between antiferromagnetic and charge density wave fluctuations in the extended Hubbard model

Petra Pudleiner, Anna Kauch, Karsten Held +1

By extending our {\it victory} implementation of the parquet approach to include non-local Coulomb interactions, we study the extended Hubbard model on the two-dimensional square l…

Interplay between magnetic and superconducting fluctuations in the doped 2d Hubbard model

Anna Kauch, Felix Hörbinger, Motoharu Kitatani +2

We study the Hubbard model on a square lattice, using the dynamical vertex approximation and the parquet approximation. These methods allow us to describe the mutual interference o…

Parquet approximation for molecules: spectrum and optical conductivity of the Pariser-Parr-Pople model

Petra Pudleiner, Patrik Thunström, Angelo Valli +3

We study a simple model system for the conjugated -bonds in benzene, the Pariser-Parr-Pople (PPP) model, within the parquet approximation (PA), exemplifying the prospects of the…
