Gate control of spin-polarized conductance in alloyed transition metal nano-contacts
Ilia N. Sivkov, Oleg O. Brovko, Ivan Rungger +1
To date, endeavors in nanoscale spintronics are dominated by the use of single-electron or single-spin transistors having at their heart a semiconductor, metallic or molecular quan…
Quantum wave mixing and visualisation of coherent and superposed photonic states in a waveguide
A. Yu. Dmitriev, R. Shaikhaidarov, V. N. Antonov +2
Superconducting quantum systems (artificial atoms) have been recently successfully used to demonstrate on-chip effects of quantum optics with single atoms in the microwave range. I…
Temperature Dependence of Spin-Split Peaks in Transverse Electron Focusing
Chengyu Yan, Sanjeev Kumar, Michael Pepper +5
We present experimental results of transverse electron-focusing measurements performed using n-type GaAs. In the presence of a small transverse magnetic field (B), electrons are fo…
Interference Effects in a Tunable Quantum Point Contact Integrated with an Electronic Cavity
Chengyu Yan, Sanjeev Kumar, Michael Pepper +5
We show experimentally how quantum interference can be produced using an integrated quantum system comprising an arch-shaped short quantum wire (or quantum point contact, QPC) of 1…
Self-synchronization Phenomena in the Lugiato-Lefever Equation
Hossein Taheri, Pascal Del'Haye, Ali A. Eftekhar +2
The damped driven nonlinear Schrödinger equation (NLSE) has been used to understand a range of physical phenomena in diverse systems. Studying this equation in the context of optic…
Direct observation of exchange-driven spin interactions in one-dimensional system
Chengyu Yan, Sanjeev Kumar, Kalarikad Thomas +6
We present experimental results of transverse electron focusing measurements performed on an n-type GaAs based mesoscopic device consisting of one-dimensional (1D) quantum wires as…
