Exact solutions for nondiffracting beams. I. The scalar theory
We present exact, nonsingular solutions of the scalar-wave equation for beams that are nondiffracting. This means that the intensity pattern in a transverse plane is unaltered by propagating in freeExpand
Exact solutions for nondiffracting beams

Comparison of Bessel and Gaussian beams.
A comparison of beam divergence and power-transport efficiency is made between Gaussian and Bessel beams when both beams have the same initial total power and the same initial full width atExpand
First-Passage-Time Distributions under the Influence of Quantum Fluctuations in a Laser
The distribution of first-passage times is calculated for a homogeneously broadened two-mode laser, that is characterized by a bistable potential. As a consequence of quantum fluctuations, such aExpand
Free energy fluxes and the Kubo–Martin–Schwinger relation
A general, multi-component Eulerian fluid theory is a set of nonlinear, hyperbolic partial differential equations. However, if the fluid is to be the large-scale description of a short-rangeExpand
Limits to resolution in time-dependent spectral analysis of pulses
We present a study of the ability of three basic spectrometers—the diffraction grating, the Fabry–Perot, and the prism—to measure the Fourier energy spectra of pulses, that is, signals that are timeExpand
Experiments with nondiffracting needle beams
We present a method for generating the nondiffracting beams predicted by Durnin 1 as well as the results of recent experiments with these beams.
Non-Equilibrium Dynamics and Weakly Broken Integrability
Motivated by dynamical experiments on cold atomic gases, we develop a quantum kinetic approach to weakly perturbed integrable models out of equilibrium. Using the exact matrix elements of theExpand
Does a photodetector always measure the rate of arrival of photons
It is pointed out that in many cases the response of a photodetector depends on the angle of the incident light beam in a way that is different from the transmissivity of the photosensitive surface.Expand
The Space of Integrable Systems from Generalised $T\bar{T}$-Deformations
We introduce an extension of the generalised T T̄ -deformation described by SmirnovZamolodchikov, to include the complete set of extensive charges. We show that this gives deformations of S-matricesExpand
