Classical Vs Quantum correlations in composite systems
Luigi Amico, Sougato Bose, Vladimir E. Korepin +1
Here we provide the contributions' abstracts published in a volume we edited as a special issue in International Journal of Modern Physics B. The volume deals with the recent progr…
Local response of topological order to an external perturbation
Alioscia Hamma, Lukasz Cincio, Siddhartha Santra +2
We study the behavior of the Rényi entropies for the toric code subject to a variety of different perturbations, by means of 2D density matrix renormalization group and analytical…
Quantum discord in the ground state of spin chains
Marcelo S. Sarandy, Thiago R. de Oliveira, Luigi Amico
The ground state of a quantum spin chain is a natural playground for investigating correlations. Nevertheless, not all correlations are genuinely of quantum nature. Here we review…
