Toward the Italian Astronomical Community's Contribution to HWO: Science, Technology, and Instrument Concepts
A. Fontana, F. Annibali, N. Antonietti +101
This paper summarizes the interest of the Italian astronomical community in the possible participation in the development of the Habitable Worlds Observatory (HWO). It is largely b…
Emulating a quantum Maxwell's demon with non-separable structured light
Edgar Medina-Segura, Paola C. Obando, Light Mkhumbuza +6
Maxwell's demon (MD) has proven an instructive vehicle by which to explore the relationship between information theory and thermodynamics, fueling the possibility of information dr…
The Tree of Light as interstellar optical transmitter system
Elisa Bazzani, Anna Valeria Guglielmi, Roberto Corvaja +8
This work aims at investigating the optical transmission system needed for such lightweight sail, taking into account the physical constraints of such unprecedented link and focusi…
Multipole-phase beams: a new paradigm for structured waves
Gianluca Ruffato, Vincenzo Grillo, Filippo Romanato
The control of structured waves has recently opened innovative scenarios in the perspective of radiation propagation and light-matter interaction. In particular, the transmission o…
A general framework for conformal transformations in electron optics
Gianluca Ruffato, Enzo Rotunno, Vincenzo Grillo
The implementation of log-pol transformation has recently introduced a new boost in electron optics with charged matter vortices, allowing to map conformally between linear and orb…
Non-paraxial design and fabrication of a compact OAM sorter in the telecom infrared
