Localised Wannier functions in metallic systems
Horia Cornean, David Gontier, Antoine Levitt +1
The existence and construction of exponentially localised Wannier functions for insulators is a well-studied problem. In comparison, the case of metallic systems has been much less…
Adiabatic currents for interacting electrons on a lattice
Domenico Monaco, Stefan Teufel
We prove an adiabatic theorem for general densities of observables that are sums of local terms in finite systems of interacting fermions, without periodicity assumptions on the Ha…
Chern and Fu-Kane-Mele invariants as topological obstructions
Domenico Monaco
The use of topological invariants to describe geometric phases of quantum matter has become an essential tool in modern solid state physics. The first instance of this paradigmatic…
Parseval frames of exponentially localized magnetic Wannier functions
Horia D. Cornean, Domenico Monaco, Massimo Moscolari
Motivated by the analysis of gapped periodic quantum systems in presence of a uniform magnetic field in dimension , we study the possibility to construct spanning sets of…
On the construction of Wannier functions in topological insulators: the 3D case
Horia D. Cornean, Domenico Monaco
We investigate the possibility of constructing exponentially localized composite Wannier bases, or equivalently smooth periodic Bloch frames, for 3-dimensional time-reversal symmet…
