Non-Hermitian off-diagonal disordered optical lattices
E. T. Kokkinakis, I. Komis, K. G. Makris +1
Within the framework of non-Hermitian photonics, we investigate the spectral and dynamical properties of one- and two-dimensional non-Hermitian off-diagonal disordered optical latt…
AIFloodSense: A Global Aerial Imagery Dataset for Semantic Segmentation and Understanding of Flooded Environments
Georgios Simantiris, Konstantinos Bacharidis, Apostolos Papanikolaou +2
Accurate flood detection from visual data is a critical step toward improving disaster response and risk assessment, yet datasets for flood segmentation remain scarce due to the ch…
Optical Tautochrone and Squeezing Dynamics in Nonuniform Lattices
Ioannis Kiorpelidis, Matthias Heinrich, Alexander Szameit +2
We present exact analogies between the tautochrone problem of classical mechanics and the squeezed states of quantum optics to optical lattices. Both phenomena emerge in the same p…
Multi-qubit Rydberg gates between distant atoms
Antonis Delakouras, Georgios Doultsinos, David Petrosyan
We propose an efficient protocol to realize multi-qubit gates in arrays of neutral atoms. The atoms encode qubits in the long-lived hyperfine sublevels of the ground electronic sta…
Shaping Cold Atom Clouds with a Vortex Beam
Arianna Bertoluzza, Sonja Lorenz, Paul Hampp +5
We introduce a method for shaping a cold atom cloud using a vortex laser beam with a polarization singularity at its center, which creates a point of vanishing intensity. Exploitin…
Continuum optical-UV and X-ray variability of AGN: current results and future challenges
Maurizio Paolillo, Iossif Papadakis
Active Galactic Nuclei (AGN) are believed to be powered by accretion of matter onto a supermassive black hole. A fundamental ingredient in shaping our understanding of AGN is their…
