TLDR
The results definitely prove that the lifetime of the cavity photons is governed by the group velocity of light in the cavity and not its phase velocity.Abstract:
We investigate experimentally the lifetime of the photons in a cavity containing a medium exhibiting strong positive dispersion. This intracavity positive dispersion is provided by a metastable helium gas at room temperature in the electromagnetically induced transparency (EIT) regime, in which light propagates at a group velocity of the order of 10000 m/s. The results definitely prove that the lifetime of the cavity photons is governed by the group velocity of light in the cavity, and not its phase velocity.read more

Quantum fluids of light
Iacopo Carusotto,Cristiano Ciuti +1 more
TL;DR: In this paper, a review of recent theoretical and experimental advances in the fundamental understanding and active control of quantum fluids of light in nonlinear optical systems is presented, from the superfluid flow around a defect at low speeds to the appearance of a Mach-Cherenkov cone in a supersonic flow, to the hydrodynamic formation of topological excitations such as quantized vortices and dark solitons at the surface of large impenetrable obstacles.

Giant gain enhancement in photonic crystals with a degenerate band edge
TL;DR: In this paper, a degenerate band edge (DBE) operator was proposed for a special class of photonic crystals supporting four modes at each frequency, called Fabry-P\'erot cavities (FPCs).

Laser gyro at quantum limit
TL;DR: In this article, it was shown that a certain fundamental limit applies to the accuracy of all optical rotation sensors which use laser light as a probe, and the same relationship is obtained from a spontaneous-emission noise formulation.

Mode-mixing quantum gates and entanglement without particle creation in periodically accelerated cavities
David Edward Bruschi,David Edward Bruschi,Jorma Louko,Jorma Louko,Daniele Faccio,Ivette Fuentes +5 more
TL;DR: In this paper, it was shown that a second resonance, which has attracted less attention since it implies negligible particle production, produces a beam splitting quantum gate leading to a resonant enhancement of entanglement which can be used as the first evidence of acceleration effects in mechanical oscillators.

Strong photon blockade with intracavity electromagnetically induced transparency in a blockaded Rydberg ensemble
TL;DR: In this article, the authors consider the dynamics of intracavity electromagnetically induced transparency (EIT) in an ensemble of strongly interacting Rydberg atoms and show that such an EIT system could exhibit very strong photon blockade effect.

Observation of electromagnetically induced transparency.
TL;DR: In this paper, the authors report the first demonstration of a technique by which an optically thick medium may be rendered transparent by applying a temporally smooth coupling laser between a bound state of an atom and the upper state of the transition which is to be made transparent.

Observation of electromagnetically induced transparency
TL;DR: The first demonstration of a technique by which an optically thick medium may be rendered transparent is reported, which results from a destructive interference of two dressed states created by applying a temporally smooth coupling laser between a bound state of an atom and the upper state of the transition which is to be made transparent.

Superluminal and Slow Light Propagation in a Room-Temperature Solid
TL;DR: It is observed that ions in mirror sites are inversely saturable and cause superluminal light propagation, whereas ions in inversion sites experience conventional saturable absorption and produce slow light.
