Thermal equilibrium can be indicated macroscopically by spatially uniform temperature and chemical potentials, but also by a microscopic property emerging from quantum entanglement.

Phys. Rev. Lett. 115, 100501 (2015) - Published 1 September, 2015
The collective excitations of a quantum many-body system of trapped ions is characterized in a new spectroscopic technique that probes the eigenmodes of the system. The technique allows the excited quasiparticles to be individually manipulated and measured.
