Experimental characterization of the hierarchy of quantum correlations in top quark pairs

Yoav Afik, Regina Demina, Alan Herrera +3

Recent results from the Large Hadron Collider have demonstrated quantum entanglement of top quark-antiquark pairs using the spin degrees of freedom. Based on the doubly differentia…

Spectroscopic Signatures of a Liouvillian Exceptional Spectral Phase in a Collective Spin

Rafael A. Molina

Non-Hermitian degeneracies of Lindblad generators (Liouvillian exceptional points) can induce non-exponential relaxation and higher-order poles in dynamical response functions. A c…

Chaos, thermalization and breakdown of quantum-classical correspondence in a collective many-body system

Ángel L. Corps, Sebastián Gómez, Pavel Stránský +2

We investigate thermalization and the quantum-classical correspondence in the collective Bose-Hubbard model, focusing on the four-site case. Our analysis of the classical phase-spa…
