Examples

  • Despite the importance of such materials to industry, only in the last several years have physicists and engineers begun to learn much about their peculiar nonequilibrium behavior as a function of time.

    Academic text (1995)
  • Nonequilibrium systems are characterized by irreversible heat losses between the system and its environment, typically a thermal bath.

  • The dissipative nature of the mechanism corresponding to the irreversible term means that even random fluctuations, such as those that might arise from a simple two-state nonequilibrium chemical reaction, can drive transport.

    Academic text (2002)
  • In a nonequilibrium state, the system cannot maintain a stable temperature or pressure.

Morphology

nonequilibrium = equilibrium (transparent) = non + equilibrium

The adjective/noun is formed by adding 'non-' to 'equilibrium', yielding the straightforward meaning 'not in equilibrium'.

Etymology

Nonequilibrium comes from non- 'not' and equilibrium 'balance', so as a noun it means a 'state' that is 'not in balance'. That's why scientists use nonequilibrium to talk about systems that are not steady and are changing.
