• Authors: Indrajith. V.S and R. Sankaranarayanan
• Abstract summary: It is shown that if the system is allowed to exchange energy with environment, the initial state evolves and settles down to uncorrelated state in limit. We have also demonstrated that fidelity based measurement induced non-locality is a useful quantity in characterizing correlated quantum states.

• Abstract: Quantum correlation of bipartite states (beyond entanglement) in presence of environment is studied for Heisenberg XYZ spin system. It is shown that if the system is allowed to exchange energy with environment, the initial state evolves and settles down to uncorrelated state in asymptotic limit. We have also demonstrated that fidelity based measurement induced non-locality is a useful quantity in characterizing correlated quantum states.

  We prove new concentration inequalities for quantum spin systems. Our results do not require the spins to be arranged in a regular lattice. We introduce a local W1 distance, which quantifies the distinguishability of two states with respect to local observables.

We find that the breakdown of the quantum-classical correspondence of particle motion, via dramatically changing the spatial structure of many-body wavefunction, leads to profound changes of the entanglement structure.

  We prove a strong exponential convergence in relative entropy of the system to equilibrium under a condition of spatial mixing. We show that our notion of spatial mixing is a consequence of the recent quantum generalization of Dobrushin and Shlosman's complete analyticity of the free-energy at equilibrium. Our results have wide-ranging applications in quantum information.

  In the quantum Zeno effect, quantum measurements can block the coherent oscillation of a two level system by freezing its state to one of the measurement eigenstates. We show that the onset of the Zeno regime is marked by a $textitcascade of transitions$ in the system dynamics as the measurement strength is increased.
