Entanglement and fidelity across quantum phase transitions in locally perturbed topological codes with open boundaries
Harikrishnan K J, Amit Kumar Pal
We investigate the topological-to-non-topological quantum phase transitions (QPTs) occurring in the Kitaev code under local perturbations in the form of local magnetic field and sp…
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…
