Logarithmic growth of peripheral entanglement concentrated via noisy measurements in a star network of spins
Jithin G. Krishnan, Harikrishnan K. J., Amit Kumar Pal
In a star-network of qubits interacting via Heisenberg interaction of XYZ-type, we demonstrate a logarithmic growth of the localizable bipartite peripheral entanglement with increa…

Estimating entanglement in 2D Heisenberg model in the strong rung-coupling limit
Chandrima B. Pushpan, Harikrishnan K. J., Prithvi Narayan +1
In this paper, we calculate entanglement in the isotropic Heisenberg model in a magnetic field on a two-dimensional rectangular zig-zag lattice in the strong rung-coupling limit, u…
