Spin transport and lack of quantisation for time-reversal symmetric insulators on the honeycomb structure
Luca Fresta, Giovanna Marcelli
We investigate spin transport in a class of time-reversal symmetric insulators on the honeycomb structure, the Kane--Mele model being an emblematic example in this class. We derive…

Longitudinal conductivity at integer quantum Hall transitions
Giovanna Marcelli, Lorenzo Pigozzi, Marcello Porta
We consider a class of two-dimensional tight binding models displaying conical intersections of the Bloch bands at the Fermi level. The setting includes the case of generic transit…
