Spatial correlations in four-wave mixing with structured light
Mateus R. L. da Motta, Sandra S. Vianna
We present a detailed theoretical treatment of four-wave mixing (FWM) in a quantized paraxial framework, capturing the multi-spatial-mode nature of the biphoton state generated in…

The Bloch Equation Generator -- SimuFÃsica
M. P. M. de Souza, G. H. H. Pavão, A. A. C. de Almeida +1
The interaction between multilevel quantum systems and coherent radiation underlies several phenomena in modern atomic optics. The formulation and solution of the Bloch equations,…

Intensity correlations in transmission and four-wave mixing signals intermediated by hot rubidium atoms
A. A. C. de Almeida, A. S. Alvarez, N. R. de Melo +3
We investigate the influence of the distribution of atom velocities in a hot rubidium sample on the correlation between field-intensity fluctuations of two independently generated…
