Toward systematic understanding of diversity of electronic properties in low-dimensional molecular solids
Solids exhibit a variety of electronic properties such as elastic, magnetic, thermodynamic,
transport properties, etc. Above all, the difference between insulating and metallic properties …

Splitting of topological charge pum** in an interacting two-component fermionic Rice-Mele Hubbard model
A Thouless pump transports an integer amount of charge when pum** adiabatically
around a singularity. We study the splitting of such a critical point into two separate critical …
