Anderson localization and momentum-space entanglement
(Iop Publishing Ltd, 2014-07-01)
We consider Anderson localization and the associated metal-insulator transition for non-interacting fermions in D = 1, 2 space dimensions in the presence of spatially correlated on-site random potentials. To assess the ...
Entanglement of excited states in critical spin chains
(IOP PUBLISHING LTDBRISTOL, 2012)
Renyi and von Neumann entropies quantifying the amount of entanglement in ground states of critical spin chains are known to satisfy a universal law which is given by the conformal field theory (CFT) describing their scaling ...
Shared information in stationary states at criticality
(IOP PUBLISHING LTD, 2010)
We consider bipartitions of one-dimensional extended systems whose probability distribution functions describe stationary states of stochastic models. We define estimators of the information shared between the two subsystems. ...
Entanglement from dissipation and holographic interpretation
(Springer, 2018-02)
In this work we study a dissipative field theory where the dissipation process is manifestly related to dynamical entanglement and put it in the holographic context. Such endeavour is realized by further development of a ...
A quantum logical and geometrical approach to the study of improper mixtures
(American Institute Of Physics, 2010-05)
We study improper mixtures from a quantum logical and geometrical point of view. Taking into account the fact that improper mixtures do not admit an ignorance interpretation and must be considered as states in their own ...
