The first gravitational-wave source from the isolated evolution of two stars in the 40–100 solar mass range p.512

Numerical simulations of the formation of binary black holes provide a framework within which to interpret the recent detection of the first gravitational-wave source and to predict the properties of subsequent binary-black-hole gravitational-wave events; the calculations predict detections of about 1,000 black-hole mergers per year once gravitational-wave observatories reach full sensitivity.

Real-time dynamics of lattice gauge theories with a few-qubit quantum computer p.516

A digital quantum simulation of a lattice gauge theory is performed on a quantum computer that consists of a few trapped-ion qubits; the model simulated is the Schwinger mechanism, which describes the creation of electron–positron pairs from vacuum.
