| + | Since in general relativity the curvature corresponds to the gravitational field, QFT in curved spacetime corresponds to a normal QFT with an external source (=the gravitational field). | ||
| + | |||
| + | For a curvature that depends on the time, we are dealing with a time varying source that can, for example, produce particles. | ||
| + | |||
| + | A proper analogy is a driven harmonic oscillator. | ||
