Authors: Sabin, Carlos Contribution: Article Journal: UNIVERSE Publication date: 2020/09/09 DOI: 10.3390/universe6090149 Abstract: We propose an experimental setup to test the effect of curved spacetime upon the extraction of entanglement from the quantum field vacuum to a pair of two-level systems. We consider two superconducting qubits coupled to a dc-SQUID array embedded into an open microwave [...]

Authors: Castrillon Lopez, Marco; Gadea, P. M.; Rosado Maria, Maria Eugenia Contribution: Article Journal: RESULTS IN MATHEMATICS Publication date: 2020/09/05 DOI: 10.1007/s00025-020-01259-4 Abstract: We classify four-dimensional connected simply-connected Lorentzian symmetric spaces M with connected nontrivial isotropy group furnishing solutions of the Einstein-Yang-Mills equations. Those solutions are built with respect to some invariant metric connection. in the [...]
