Abstract

Shortly after Hawking’s prediction of thermal radiation from black holes; it became apparent that observers in accelerating frames should see a Planck distribution of electromagnetic radiation (Unruh radiation). Since an acceleration g =980 cm/sec 2 produces a radiation temperature of only ∼4×10 -20 K; the detection of such thermal radiation is a major challenge. A nonlinear optical medium whose index of refraction is changing rapidly with time accelerates zero-point quantum fluctuations. The sudden ionization of a gas or a semiconductor crystal to generate a plasma on a subpicosecond time scale can produce a reference frame accelerating at ∼10 20 g relative to an inertial frame.
