Electronic transport in one dimension
The talk will have three parts, discussing electronic transport in three different one-dimensional systems: (i) A junction of three interacting quantum wires has many interesting and distinct transport properties compared to a single quantum wire with a scattering centre. Classification of Y-junctions and interesting results on conductance of Y-junctions will be mainly discussed. (ii)-Periodically driven one-dimensional quantum wires, can pump charge. Results on charge pumping in closed and open systems will be contrasted. Further, pumping on the edge of quantum spin Hall insulators will be discussed. (iii) A recent proposal to enhance crossed Andreev reflection in “normal metal - superconductor - normal metal” will be discussed.
