Reservoir Computing Using Autonomous Boolean Networks Realized on Field-Programmable Gate Arrays
In this chapter, we consider realizing a reservoir computer on an electronic chip that allows for many tens of network nodes whose connection topology can be quickly reconfigured. The reservoir computer displa...

Superluminal Communication in Quantum Mechanics
One consequence of the special theory of relativity is that no information can be transmitted between two parties in a time shorter than it would take light, propagating through vacuum, to travel between the p...

Causality in Superluminal Pulse Propagation
The theory of electromagnetism for wave propagation in vacuum, as embodied by Maxwell’s equations, contains physical constants that can be combined to arrive at the speed of light in vacuum c. As shown by Einstei...

Pulse propagation in a high-gain bichromatically-driven Raman amplifier
Using intense electromagnetic fields, it is now possible to tailor the absorption. amplification, and dispersion properties of multi-level atoms [1]. Dramatic examples include the reduction of the group velocity ...

Dynamics of a two-photon laser
The high degree of temporal coherence of laser light arises from a complex interplay between the fundamental light-matter interactions of absorption, spontaneous emission, and stimulated emission. The coherenc...

Polarization dynamics of a two-photon laser
The high degree of temporal coherence of laser light arises from a complex interplay between the fundamental light-matter interactions of absorption, spontaneous emission, and stimulated emission. The coherenc...

Observation of 30% Continuous-Wave Two-Photon Optical Amplification
Two-photon lasers have intrigued researchers for years because the dynamical behavior of this new class of highly nonlinear oscillator is very different from normal one-photon lasers. Experimental tests of the...

Chapter
The Two-Photon Laser
We explain in simple terms the behavior of two-photon lasers and describe recent results that have lead to the realization of the first continuous-wave two-photon optical laser. We stress the differences betwe...

Bistability and Chaos in Counterpropagating Laser Beams
In this paper we describe experimental observations which demonstrate that multi-stability and chaotic instabilities can occur in cavity-less nonlinear optical systems. In particular, we have experimentally in...

A Novel Technique for Resonantly Enhanced Sum-Frequency Generation Involving Rydberg Atomic States
Experimental evidence is presented that demonstrates the usefulness of atomic Rydberg states in resonantly enhanced, nonlinear optical mixing. This work provides verification of a recent prediction that large ...
