Aspects of symplectic dynamics and topology: gauge anomalies, chiral kinetic theory and transfer matrices
… The second part describes a generalized transfer matrix formalism for noninteracting tight-binding models. The formalism is used to study the bulk and edge spectra, both of which are encoded in the spectrum of the transfer matrices, for some of the common tight-binding models for …
