Renormalization group study of transport through a superconducting junction of multiple one-dimensional quantum wires
Sourin Das, Sumathi Rao, Arijit Saha
We investigate transport properties of a superconducting junction of many () one-dimensional quantum wires. We include the effectofelectron-electron interaction within the…
Spintronics with NSN Junction of one-dimensional quantum wires : A study of Pure Spin Current and Magnetoresistance
Sourin Das, Sumathi Rao, Arijit Saha
We demonstrate possible scenarios for production of pure spin current and large tunnelling magnetoresistance ratios from elastic co-tunnelling and crossed Andreev reflection across…
Quantised charge pumping through multiple quantum dots
Argha Banerjee, Sourin Das, Sumathi Rao
We study electron pumping through a system of barriers, whose heights are deformed adiabatically. We derive a simple formula for the pumped charge in terms of the total reflect…
Results from bosonisation for resonant tunneling through a quantum dot in an Aharanov-Bohm ring
P. Durganandini, Sumathi Rao
We study coherent charge tunneling through a one-dimensional interacting ring with a one-dimensional quantum dot embedded in one of its arms through bosonisation. The symmetries of…
The Fractional Quantum Hall Effect
Sumathi Rao
We give a brief introduction to the phenomenon of the Fractional Quantum Hall effect, whose discovery was awarded the Nobel prize in 1998. We also explain the composite fermion pic…
