Fractional lattice charge transport
Scientific Reports, 2017 AbstractWe consider the dynamics of noninteracting quantum particles on a square lattice in the presence of a magnetic flux α and a dc electric field E oriented along the lattice diagonal. In general, the adiabatic dynamics will be characterized by Bloch oscillations in the electrical field direction and dispersive ballistic transport in the ...

Two distinctive regimes in the charge transport of a magnetic topological ultra thin film
New Journal of Physics, 2020 The effect of the magnetic impurities on the charge transport in a magnetic topological ultra-thin film (MTF) is analytically investigated by applying the semi-classical Boltzmann framework through a modified relaxation-time approximation.
