Inertial motion superradiance, the emission of radiation by an initially unexcited system moving inertially but superluminally through a medium, has long been known. Rotational superradiance, the amplification of radiation by a rotating rigid object, was recognized much later, principally in connection with black hole radiances. Here we review the principles of inertial motion superradiance and prove thermodynamically that the Ginzburg-Frank condition for superradiance coincides with the… Expand

A modern approach to superradiance

- Physics
- 2016

A bstractIn this paper, we provide a simple and modern discussion of rotational super-radiance based on quantum field theory. We work with an effective theory valid at scales much larger than the… Expand

Penrose process, superradiance, and ergoregion instabilities

- Physics

Superradiant scattering is a radiation enhancement process that takes place in many contexts, and which has recently found exciting applications in astro and particle physics. In the framework of… Expand

Superradiant scattering by a black hole binary

- Physics
- 2019

I present evidence of a novel guise of superradiance that arises in black hole binary spacetimes. Given the right initial conditions, a wave will be amplified as it scatters off the binary. This… Expand

The analogy between the propagation of a massless scalar field in curved spacetime and the propagation of sound waves in a Bose-Einstein Condensate (BEC) gives rise to the possibility of observing… Expand

Rotational quantum friction in superfluids: Radiation from object rotating in superfluid vacuum

- Physics
- 1999

The friction experienced by a body rotating in a superfluid liquid at T=0 is discussed. The effect is analogous to the amplification of electromagnetic radiation and spontaneous emission by a body or… Expand

Generalized superradiant scattering

- Physics
- 2009

We analyze the necessary and sufficient conditions for the occurrence of superradiance. Starting with a wave equation we examine the possibility of superradiance in terms of an effective potential… Expand

Superradiance in a ghost-free scalar theory

- Physics
- 2018

We study superradiance effect in the ghost-free theory. We consider a scattering of a ghost-free scalar massless field on a rotating cylinder. We assume that cylinder is thin and empty inside, so… Expand

Quantum Cherenkov radiation and noncontact friction

- Physics
- 2013

We present a number of arguments to demonstrate that a quantum analog of Cherenkov effect occurs when two dispersive objects are in relative motion. Specifically we show that two semi-infinite plates… Expand

Reinventing the Zel'Dovich wheel

- Physics
- 2019

After reviewing the pioneering work by Zel'Dovich in which radiation is amplified perpendicular to the axis of a rotating conductor, we consider an alternative scattering arrangement. We demonstrate… Expand

Black hole lasers, a mode analysis

- Physics
- 2010

We show that the black hole laser effect discovered by Corley and Jacobson should be described in terms of frequency eigenmodes that are spatially bound. The spectrum contains a discrete and finite… Expand
