Two simple textures of the magic neutrino mass matrix
Kanwaljeet S. Channey, Sanjeev Kumar
The Tri-Bimaximal (TBM) mixing predicts a vanishing . This can be attributed to the inherited symmetry of TBM mixing. We break its symmetry by adding a complex…
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…
Cluster mean field study of the Heisenberg model for CuInVO
Ayushi Singhania, Sanjeev Kumar
Motivated by the experimental report of unusual low temperature magnetism in quasi one-dimensional magnet CuInVO, we present results of a cluster mean-field study on a spin-$1/…
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…
