Nonadiabatic charge pumping in a one-dimensional system of noninteracting electrons by an oscillating potential
Amit Agarwal, Diptiman Sen
Using a tight-binding model, we study one-parameter charge pumping in a one-dimensional system of non-interacting electrons. An oscillating potential is applied at one site while a…

Charge transport in a Tomonaga-Luttinger liquid: effects of pumping and bias
Amit Agarwal, Diptiman Sen
We study the current produced in a Tomonaga-Luttinger liquid by an applied bias and by weak, point-like impurity potentials which are oscillating in time. We use bosonization to pe…
