A modelling study across the Italian regions: Lockdown, testing strategy, colored zones, and skew-normal distributions. How a numerical index of pandemic criticality could be useful in tackling the CoViD-19
Stefano De Leo, Manoel P. Araujo
As Europe is facing the second wave of the CoViD-19 pandemic, each country should carefully review how it dealt with the first wave of outbreak. Lessons from the first experience s…
Power oscillations induced by the relative Goos-Haenchen phase
Manoel P. Araújo, Stefano De Leo, Gabriel G. Maia +1
By using an optical interferometer composed of a dielectric laser ellipsometer, to change the optical response of transverse electric and magnetic incident radiation, and two polar…
Optical weak measurements without removing the Goos-Haenchen phase
Manoel P. Araújo, Stefano De Leo, Gabriel G. Maia
Optical weak measurements are a powerful tool for measuring small shifts of optical paths. When applied to the measurement of the Goos-Haenchen shift, in particular, a special step…
Optimizing weak measurements to detect angular deviations
Manoel P. Araújo, Gabriel G. Maia, Stefano De Leo
We analyze and compare the angular deviations for an optical beam reflected by and transmitted through a dielectric triangular prism. The analytic expressions derived for the angul…
Transversal symmetry breaking and axial spreading modification for Gaussian optical beams
Manoel Araujo, Stefano De Leo, Marina Lima
For a long time it was believed there was no reason to include the geometrical phase in studying the propagation of gaussian optical beams through dielectric blocks. This can be ju…
Closed form expression for the Goos-Haenchen lateral displacement
Manoel P. Araujo, Stefano De Leo, Gabriel G. Maia
The Artmann formula provides an accurate determination of the Goos-Haenchen lateral displacement in terms of the light wavelength, refractive index and incidence angle. In the tota…
Axial dependence of optical weak measurements in the critical region
Manoel P. Araujo, Stefano De Leo, Gabriel G. Maia
The interference between optical beams of different polarizations plays a fundamental role in reproducing the optical analog of the electron spin weak measurement. The extraordinar…
The frequency crossover for the Goos-Hanchen shift
Manoel Araujo, Silvania Carvalho, Stefano De Leo
For total reflection, the Goos-Hanchen (GH) shift is proportional to the wavelength of the laser beam. At critical angles, such a shift is instead proportional to the square root o…
The asymmetric Goos-Hänchen effect
Manoel P. Araujo, Silvânia A. Carvalho, Stefano De Leo
We show in which conditions optical gaussian beams, propagating throughout an homogeneous dielectric right angle prism, present an asymmetric Goos-Hänchen (GH) effect. This asymmet…
