Iterative approach for high-quality binary intensity hologram generation in augmented reality applications
Anik Ghosh, Matteo Ziliani, Marco Astarita +8
Binary amplitude spatial light modulators, such as digital micromirror devices (DMDs), are increasingly relevant for computer generated holography due to their high refresh rates,…
Zero-Order Diffraction Suppression in Full Field-of-View Computer Generated Holography: A Camera In the Loop Interferometric Approach
Alessandro Cerioni, Samuele Trezzi, Marco Astarita +6
We introduce a novel interferometric approach for suppressing zero-order diffraction (ZOD) in phase-only computer-generated holography. The technique relies on the destructive inte…
Identification of Resonant States via the Generalized Virial Theorem
Luigi Genovese, Alessandro Cerioni, Maxime Morinière +1
The numerical extraction of resonant states of open quantum systems is usually a difficult problem. Regularization techniques, such as the mapping to complex coordinates or the add…
Accurate Complex Scaling of Three Dimensional Numerical Potentials
Alessandro Cerioni, Luigi Genovese, Ivan Duchemin +1
The complex scaling method, which consists in continuing spatial coordinates into the complex plane, is a well-established method that allows to compute resonant eigenfunctions of…
Efficient and accurate solver of the three-dimensional screened and unscreened Poisson's equation with generic boundary conditions
Alessandro Cerioni, Luigi Genovese, Alessandro Mirone +1
We present an explicit solver of the three-dimensional screened and unscreened Poisson's equation which combines accuracy, computational efficiency and versatility. The solver, bas…
Cosmological Perturbations in the "Healthy Extension'' of Horava-Lifshitz gravity
Alessandro Cerioni, Robert H. Brandenberger
We study linear cosmological perturbations in the ``healthy extension'' of Horava-Lifshitz gravity which has recently been analyzed \cite{BPS2}. We find that there are two degrees…
