Non-equilibrium thermodynamics of collapse models in the strongly non-Gaussian regime

Standard objective collapse models offer a unified approach to the quantum measurement problem but predict an unphysical, indefinite increase in the energy of the system. The dissipative Di ´osi-Penrose (dDP) model resolves this heating issue by introducing a linear friction mechanism. However, this modification induces complex, non-Gaussian phase-space dynamics. We rigorously establish the thermodynamic consistency of this friction mechanism - extended to the Continuous Spontaneous Loca...

Non-equilibrium thermodynamics of quantum Brownian motion

We rigorously analyze the non-equilibrium thermodynamic behavior of various formulations of quantum Brownian motion (QBM) using the framework of stochastic thermodynamics. While the widely used Caldeira-Leggett master equation exhibits desirable thermodynamic features — such as the fulfilment of a detailed balance — it fails to ensure complete positivity. In contrast, several completely positive and trace-preserving (CPTP) extensions turn out to be thermodynamically controversial. We sho...

CHARACTERIZING STELLAR FLARES IN THE ARIEL TARGETS: ACTIVITY ANALYSIS AND TRANSIT PROBABILITIES

The objective of this work is to investigate stellar flaring activity in confirmed exoplanet host stars of the Ariel Mission Candidate Sample (MCS), with the aim of assessing the impact of stellar flares on transit spectroscopy observations. From the Ariel sample, we select 290 nearby systems (d < 200 pc) with available TESS light curves, representative of the current Ariel target population. We analyze the light curves using an iterative Gaussian Process detrending and flare characterizat...

Synthesis and Characterization of Dye-Sensitized Solar Cells Enhanced with Carbon Dots for Improved Performance

A new dye-sensitized solar cell (DSSC) was fabricated by incorporating a percentage of 2% of dialyzed carbon dots (CDs) made by urea and citric acid as precursor (100:1) into a standard Ruthenizer 620 dye system. The carbon dots were subjected to a dialysis purification process before integration. The resulting DSSCs exhibited a power performance enhancement compared to cells sensitized with only Ruthenizer 620. This improvement is at-tributed to favorable bandgap adaptation between the...

Extending Multi-Sensor Remote Sensing Approaches for Landslide Timing Analysis in Google Earth Engine

The dating of landslides allows the reconstruction of slope dynamics and link landslide events to the geomorphological processes that triggered them. In many areas, the timing of landslide initiation is uncertain due to limited observational data. In the absence of such information, the analysis of satellite remote sensing time series provides an essential tool for landslide dating, thanks to the availability of multi-sensor observations. In this context, Google Earth Engine (GEE) provides a ...
