Non-Markovian dynamics of a qubit due to accelerated light in a lattice

We study the emission dynamics of a qubit weakly coupled to a one-dimensional coupled-cavity array with a synthetic frequency gradient that mimics a uniform force on photons. This engineered force induces Bloch oscillations, leading to distinct emission regimes. For strong gradients, the qubit exhibits reversible, chiral emission resembling a Jaynes-Cummings model, selectively exciting the array to one side depending on the qubit frequency. For weaker gradients, non-Markovian decay with reviv...

A susceptibility oriented approach for regional landslide inventory implementation in Sicily

Landslide inventories are mandatory both for picturing the current slope instability status and enabling effective calibration of predictive susceptibility/hazard maps. However, in regions characterized by very high landslide susceptibility conditions, frequently, the inventories are biased as they almost exclusively include landslides which have been noticed and reported for having produced damages, resulting vulnerability/risk oriented. Strategies for landslide hazard management have to be ...

Objective River Segmentation Based on Sinuosity and Confinement Indices: A Multi-Scale Geomorphological Approach with Applications to Sicilian Rivers

European States have transposed the Water Framework Directive (2000/60/EC), adapting it to their ecosystems and river morphologies. While the Directive allows flexibility in methodological choices, all Member States must subdivide watercourses into homogeneous sections, a key requirement for their characterisation and management. Nonetheless, the choice of scale of analysis can significantly affect river segmentation and characterization. This study proposes an approach based on the Sinuosity...

Flow, pressure and pockmarks: assessment of gravitative instabilities by Factor Of Safety (FOS)

Pockmarks are depressions on the seafloor that represent the vent of fluid migration pathways. Their morphological features are highly variable, reflecting the wide range of geological settings in which they occur. In the Gulf of Palermo, pockmarks are located along the continental slope at depths between 230 and 390 m.b.s.l. and near the coastline (5.8 km). Building on previous investigations, this study focuses on the interpretation of acoustic and seismic geophysical data collected in th...
