Changes in anthropogenic aerosols during the first wave of COVID-19 lockdowns in the context of long-term historical trends at 51 AERONET stations
Robert Blaga, Delia Calinoiu, Gavrila Trif-Tordai
A quasi-consensus has steadily formed in the scientific literature on the fact that the prevention measures implemented by most countries to curb the 2020 COVID-19 pandemic have le…
Diffuse fraction as a tool for exploring the sensitivity of parametric clear-sky models to changing aerosol conditions
Robert Blaga, Oana Mares, Eugenia Paulescu +6
Aerosols' impact on the performance of a clear-sky solar irradiance model is often evaluated from the perspective of the overall accuracy of estimates. This study assesses the aero…
Field calibration and analysis of a low-cost sensor network based on the existing air quality infrastructure of a city
Robert Blaga
Low-cost particulate matter sensors (LCS) are an important source of air quality data, improving the spatial and temporal resolution of data gathered by sparsely placed official mo…
A methodology for realistic estimation of the aerosol impact on the solar potential
Robert Blaga, Delia Calinoiu, Marius Paulescu
The atmospheric aerosol loading may significantly influence the performance in solar power production. The impact can be very different both in space (even in short distance) and t…
The response of a Unruh-deWitt particle detector in a thin-shell wormhole spacetime
Robert Blaga
We investigate the transition probability of a Unruh-deWitt particle detector evolving in flat space and in a wormhole spacetime, in various scenarios. In Minkowski space, we look…
High-order quadrature-based lattice Boltzmann models for the flow of ultrarelativistic rarefied gases
Victor E. Ambrus, Robert Blaga
We present a systematic procedure for the construction of relativistic lattice Boltzmann models (R-SLB) appropriate for the simulation of flows of massless particles. Quadrature ru…
Quadrature-based Lattice Boltzmann Model for Relativistic Flows
Robert Blaga, Victor E. Ambrus
A quadrature-based finite-difference lattice Boltzmann model is developed that is suitable for simulating relativistic flows of massless particles. We briefly review the relativist…
Quantum Larmor radiation in de Sitter spacetime
Robert Blaga, Sergiu Busuioc
We study the radiation emitted by inertial charge evolving on the expanding de Sitter spacetime. Performing a perturbative calculation, within scalar quantum electrodynamics (sQED)…
Relativistic rotating Boltzmann gas using the tetrad formalism
Victor E. Ambrus, Robert Blaga
We consider an application of the tetrad formalism introduced by Cardall et al. [Phys. Rev. D 88 (2013) 023011] to the problem of a rigidly rotating relativistic gas in thermal equ…
One-photon pair production on the expanding de Sitter spacetime
Robert Blaga
We study the one-photon scalar pair production QED process on the expanding de Sitter spacetime. Using perturbation theory, we obtain the transition probability and study its prope…
Radiation of inertial scalar particles in the de Sitter universe
Robert Blaga
We investigate the radiation from an inertial scalar particle evolving in a de Sitter expanding Universe. In the context of scalar QED the process is generated by the first order t…
