Conductance of Tomonaga-Luttinger liquid wires and junctions with resistances
Abhiram Soori, Diptiman Sen
We study the effect that resistive regions have on the conductance of a quantum wire with interacting electrons which is connected to Fermi liquid leads. Using the bosonization for…
Line junction in a quantum Hall system with two filling fractions
Diptiman Sen, Amit Agarwal
We present a microscopic model for a line junction formed by counter or co-propagating single mode quantum Hall edges corresponding to different filling factors. The ends of the li…
Scattering of electrons from an interacting region
Abhishek Dhar, Diptiman Sen, Dibyendu Roy
We address the problem of transmission of electrons between two noninteracting leads through a region where they interact (quantum dot). We use a model of spinless electrons hoppin…
Quasi-particle propagation in quantum Hall systems
Diptiman Sen, Michael Stone, Smitha Vishveshwara
We study various geometrical aspects of the propagation of particles obeying fractional statistics in the physical setting of the quantum Hall system. We find a discrete set of zer…
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…
