Collective multipole-like signatures of entanglement in symmetric N-qubit systems
A. R. Usha Devi, R. Prabhu, A. K. Rajagopal
A cogent theory of collective multipole-like quantum correlations in symmetric multiqubit states is presented by employing SO(3) irreducible spherical tensor representation. An arb…

Electron Spin Dynamics in a Quantum Dot due to Hyperfine Coupling with Nuclei in the Dot - An Exact Analysis
A. K. Rajagopal
The time-dependent Schrodinger equation of a many particle spin system consisting of an electron in a quantum dot interacting with the spins of the nuclei (N) in the dot due to hyp…

Constraints on the uncertainties of entangled symmetric qubits
A. R. Usha Devi, M. S. Uma, R. Prabhu +1
We derive necessary and sufficient inseparability conditions imposed on the variance matrix of symmetric qubits. These constraints are identified by examining a structural parallel…
