Quantum non-equilibrium

Quantum non-equilibrium is a concept within stochastic formulations of the De Broglie–Bohm theory of quantum physics.

Quantum non-equilibrium:

\rho (X,t)\neq |\psi (X,t)|^{2}

Relaxation to quantum equilibrium:

\rho (X,t)\to |\psi (X,t)|^{2}

Quantum equilibrium hypothesis:

\rho (X,t)=|\psi (X,t)|^{2}

with

\rho (X,t)

and

\psi (X,t)

representing the wave function.
