Magnetoresistance in an electronic cavity coupled to one-dimensional systems
Chengyu Yan, Sanjeev Kumar, Patrick See +5
In this work, we performed magnetoresistance measurement in a hybrid system consisting of an arc-shaped quantum point contact (QPC) and a flat, rectangular QPC, both of which toget…
Incipient singlet-triplet states in a hybrid mesoscopic system
Chengyu Yan, Sanjeev Kumar, Michael Pepper +5
In the present work we provide an easily accessible way to achieve the singlet-triplet Kondo effect in a hybrid system consisting of a quantum point contact (QPC) coupled to an ele…
Imaging the zigzag Wigner crystal in confinement-tunable quantum wires
Sheng-Chin Ho, Heng-Jian Chang, Chia-Hua Chang +9
The existence of Wigner crystallization, one of the most significant hallmarks of strong electron correlations, has to date only been definitively observed in two-dimensional syste…
Coherent Spin Amplification Using a Beam Splitter
Chengyu Yan, Sanjeev Kumar, Kalarikad Thomas +6
We report spin amplification using a capacitive beam splitter in n-type GaAs where the spin polarization is monitored via transverse electron focusing measurement. It is shown that…
