Charged Compact Boson Stars and Shells in the Presence of a Cosmological Constant
Sanjeev Kumar, Usha Kulshreshtha, Daya Shankar Kulshreshtha
In this work we study the boson stars and boson shells in a theory involving massive complex scalar fields coupled to the U(1) gauge field and gravity in a conical potential in the…
Some New Results on Charged Compact Boson Stars
Sanjeev Kumar, Usha Kulshreshtha, Daya Shankar Kulshreshtha +2
In this work we present some new results obtained in a study of the phase diagram of charged compact boson stars in a theory involving a complex scalar field with a conical potenti…
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…
Phenomenological implications of two simple modifications to Tri-Bimaximal mixing
Kanwaljeet S. Channey, Sanjeev Kumar
We study the phenomenological implications of breaking the Tri-Bimaximal (TBM) mixing in such a way that either first or second column of TBM mixing matrix remains invariant. We pr…
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…
