Angular-dependent Andreev reflection on a polaritonic superfluid
I. Septembre, D. D. Solnyshkov, G. Malpuech
We study analytically an analog of the Andreev reflection at a normal-superfluid interface. The polariton gapped superfluid region is achieved by quasi-resonant optical pumping. Th…
The Proxy Step-size Technique for Regularized Optimization on the Sphere Manifold
Fang Bai, Adrien Bartoli
We give an effective solution to the regularized optimization problem , where is constrained on the unit sphere $\Vert \bo…
A physical model and a Monte Carlo estimate for the specific intensity spatial derivative, angular derivative and geometric sensitivity
Paule Lapeyre, Zili He, Stéphane Blanco +11
Starting from the radiative transfer equation and its usual boundary conditions, the objective of this work is to design Monte Carlo algorithms estimating the specific intensity sp…
Procrustes Analysis with Deformations: A Closed-Form Solution by Eigenvalue Decomposition
Fang Bai, Adrien Bartoli
Generalized Procrustes Analysis (GPA) is the problem of bringing multiple shapes into a common reference by estimating transformations. GPA has been extensively studied for the Euc…
