A complete characterization of mixed state entanglement using probability density functions
Shanthanu Bhardwaj, V. Ravishankar
We propose that the entanglement of mixed states is characterised properly in terms of a probability density function . There is a need for such a measure…

Decoherence of two-electron spin states in quantum dots
D. D. Bhaktavatsala Rao, V. Ravishankar, V. Subrahmanyam
The time evolution of spin states of two electrons interacting with a nuclear spin bath in a quantum dot system is studied. The hyperfine interaction between the electrons and the…
