AbstractThe relaxation behaviour of isolated quantum systems taken out of equilibrium is among the most intriguing questions in many-body physics1. Quantum systems out of equilibrium typically relax to thermal equilibrium states by scrambling local information and building up entanglement entropy.

A new binding mechanism between trapped laser-cooled ions and atoms has been observed. This advancement offers a novel control knob over chemical reactions and inelastic processes on the single particle limit. The formation of molecules is a fundamental process that can be found in a wide variety of systems. In free space, molecular formation usually requires the presence of a third particle, which carries away the binding energy of the newly formed complex.
