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…
A new paradigm for the quantum spin Hall effect at high temperatures
Gang Li, Werner Hanke, Ewelina M. Hankiewicz +5
The quantum spin Hall effect (QSHE) has formed the seed for contemporary research on topological quantum states of matter. Since its discovery in HgTe/CdTe quantum wells and AlGaAs…
Testing Topological Protection of Edge States in Hexagonal Quantum Spin Hall Candidate Materials
Fernando Dominguez, Benedikt Scharf, Gang Li +5
We analyze the detailed structure of topological edge mode protection occuring in hexagonal quantum spin Hall (QSH) materials. We focus on bismuthene, antimonene, and arsenene on a…
