Natural sciences, Physical sciences, Physics Of, pertaining to, or being a theory that describes a physical system by dividing it into two parts, one described by classical physics and the other by either relativistic or quantum mechanical physics.
- The semiclassical approach to the relativistic theory has been recently worked out by several authors and the #92;hbar² corrections to the earlier established TF relativistic theory have been derived¹⁷⁻¹⁹.1994, X.

Hu, Enric Verdaguer, Semiclassical and Stochastic Gravity, Cambridge University Press, page 337, Whereas semiclassical gravity is based on the semiclassical Einstein equation with sources given by the expectation value of the stress-energy tensor of quantum fields, stochastic semiclassical gravity is based on the Einstein—Langevin equation, which has in addition sources due to the noise kernel.
