Nuclear magnetic resonance probes for the Kondo scenario for the 0.7 feature in semiconductor quantum point contact devices
V. Tripathi, N. R. Cooper
We propose a probe based on nuclear relaxation and Knight shift measurements for the Kondo scenario for the "0.7 feature" in semiconductor quantum point contact (QPC) devices. We s…
Theory of NMR in semiconductor quantum point contact devices
N. R. Cooper, V. Tripathi
We describe how a local non-equilibrium nuclear polarisation can be generated and detected by electrical means in a semiconductor quantum point contact device. We show that measure…
Dynamic nuclear polarisation in biased quantum wires with spin-orbit interaction
V. Tripathi, A. C. H. Cheung, N. R. Cooper
We propose a new method for dynamic nuclear polarisation in a quasi one-dimensional quantum wire utilising the spin-orbit interaction, the hyperfine interaction, and a finite sourc…
Thermal transport in a granular metal array
V. Tripathi, Y. L. Loh
We obtain the Kubo formula for the electronic thermal conductivity kappa(T) of a granular metal array at low temperatures for the Ambegaokar-Eckern-Schoen (AES) model and study the…
Effective charging energy for a regular granular metal array
Y. L. Loh, V. Tripathi, M. Turlakov
We study the Ambegaokar-Eckern-Schön (AES) model for a regular array of metallic grains coupled by tunnel junctions of conductance and calculate both paramagnetic and diamagnet…
Coulomb blockade and quantum tunnelling in the low-conductivity phase of granular metals
V. Tripathi, M. Turlakov, Y. L. Loh
We study the effects of Coulomb interaction and inter-grain quantum tunnelling in an array of metallic grains using the phase-functional approach for temperatures well below th…
