Study of two-spin entanglement in singlet states
M. Q. Lone, A. Dey, S. Yarlagadda
We study the entanglement properties of two-spin subsystems in spin-singlet states. The average entanglement between two spins is maximized in a single valence-bond (VB) state. On…

Decoherence in an infinite range Heisenberg model
A. Dey, M. Q. Lone, S. Yarlagadda
We study decoherence in an infinite range Heisenberg model (IRHM) in the two situations where the system is coupled to a bath of either local optical phonons or global optical phon…
