Abstract: The behavior of bipartite and tripartite entanglement in Heisenberg $$XXZ+h$$XXZ+h spins chain is investigated with the size of system using the approach of quantum renormalization group method. In thermodynamics limit, both types of entanglement exhibit… read more here.

Abstract: We study the matrix elements of local operators in the eigenstates of the integrable XXZ chain and of the quantum-chaotic model obtained by locally perturbing the XXZ chain with a magnetic impurity. We show that,… read more here.

Abstract: We theoretically propose and experimentally demonstrate the use of motional sidebands in a trapped ensemble of ^{87}Rb atoms to engineer tunable long-range XXZ spin models. We benchmark our simulator by probing a ferromagnetic to paramagnetic… read more here.
