Intensity correlations and mesoscopic fluctuations of diffusing photons in cold atoms

open access: yes, 2006
We study the angular correlation function of speckle patterns that result from multiple scattering of photons by cold atomic clouds. We show that this correlation function becomes larger than the value given by Rayleigh law for classical scatterers ...

Open letter: The need for a site‐based biodiversity standard measuring and certifying impacts from nature‐based projects

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Despite growing investment in restoration, weak accountability and poor biodiversity monitoring mean many projects fail to achieve ecological recovery. The Global Biodiversity Standard (TGBS) offers a practical way to ensure that restoration finance delivers measurable gains for nature.

Algunas consideraciones sobre el argumento de indispensabilidad en matemáticas [PDF]

open access: yes, 2002
La tesis de indispensabilidad se toma habitualmente como un argumento (posiblemente el mejor) para defender el realismo matemático. La propuesta se asocia con Quine y Putnam, y establece que, en tanto en cuanto las entidades matemáticas se muestran ...
