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…
Sleuthing Hidden Order
V. Tripathi, P. Chandra, P. Coleman
Physicists have long debated whether the hidden order in URu2Si2 is itinerant or localized, and it remains inaccessible to direct external probes. Recent observation of an overdamp…
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…
Magnetic field induced Coulomb blockade in small disordered delta-doped heterostructures
V. Tripathi, M. P. Kennett
At low densities, electrons confined to two dimensions in a delta-doped heterostructure can arrange themselves into self-consistent droplets due to disorder and screening effects.…
