Tunable quantum anomalous Hall effect in fullerene monolayers
Leonard Werner Pingen, Jiaqi Wu, Bo Peng
Nearly four decades after its theoretical prediction, the search for material realizations of quantum anomalous Hall effect (QAHE) remains a highly active field of research. Many m…
Altermagnetic Shastry-Sutherland fullerene networks
Jiaqi Wu, Alaric Sanders, Rundong Yuan +1
The interplay between quantum magnetism and many-body physics is of fundamental importance in condensed matter physics. %Magnetic exchange interactions in frustrated lattices give…
Negative and positive anisotropic thermal expansion in 2D fullerene networks
Armaan Shaikh, Jiaqi Wu, Bo Peng
We find a design principle for tailoring thermal expansion properties in nearly-spherical molecular networks. Using 2D fullerene networks as a representative system, we realize pos…
Symmetry-induced magnetism in fullerene monolayers
Jiaqi Wu, Leonard Werner Pingen, Timothy K. Dickens +1
Using molecular orbital theory, we introduce magnetism in pure-carbon, charge-neutral fullerene monolayers which are otherwise non-magnetic. By controlling either molecular or latt…
