The '''Zeldovich effect''' (also known as '''Zeldovich amplification''' or '''Zeldovich radiation''') is a [[physical phenomenon]] in which waves, such as [[Electromagnetic radiation|electromagnetic]], [[Acoustic wave|acoustic]], or [[Gravitational wave|gravitational waves]], are amplified rather than absorbed when they interact with a [[Rotation|rotating]], absorbing object. Predicted by Soviet physicist [[Yakov Zeldovich]] in 1971, the effect occurs when the rotation speed of the object exceeds the [[angular frequency]] of the incident wave. The effect is considered a classical analogue to black hole [[superradiance]] and is closely related to the [[Penrose process]]. While theoretically established for decades, it was first experimentally verified with acoustic waves in 2020 and with electromagnetic waves in 2024. |

The core principle of the Zeldovich effect lies in the rotational [[Doppler shift]]. When a wave carrying [[orbital angular momentum]] strikes a rotating body, the frequency of the wave as seen by the rotating body is shifted. For an incident wave with an angular frequency , an [[angular momentum]] number of and an interacting with a body rotating at an angular velocity of , the condition for amplification is: |
