DOI: 10.1007/jhep10(2020)025
Abstract: Radiatively-induced gravitational leptogenesis is a potential mechanism to ex- plain the observed matter-antimatter asymmetry of the universe. Gravitational tidal effects at the quantum loop level modify the dynamics of the leptons in curved spacetime and… read more here.

DOI: 10.1063/1.5025646
Abstract: One of the most challenging problems in network science is to accurately detect communities at distinct hierarchical scales. Most existing methods are based on structural analysis and manipulation, which are NP-hard. We articulate an alternative,… read more here.

DOI: 10.1093/mnras/stad1038
Abstract: Most stars in our Galaxy form in stellar aggregates, which can become long-lived structures called open clusters (OCs). Along their dynamical evolution, their gradual depletion leave some imprints on their structure. In this work, we… read more here.

DOI: 10.1093/mnras/stad1562
Abstract: To study time-dependent phenomena of plasma surrounding a non-rotating black hole with a dipolar magnetic field, we have developed a fully set of 3+1 formalism of generalised general relativistic magnetohydrodynamic (GRMHD) equations. The general relativistic… read more here.

DOI: 10.1093/mnras/stw3381
Abstract: According to the standard model of cosmology, galaxies are embedded in dark matter halos which are made of particles beyond the standard model of particle physics, thus extending the mass and the size of the… read more here.

DOI: 10.1093/mnras/sty2502
Abstract: We have selected archival observational data for several O and B trapezia in the Milky Way. For each of the main components of the trapezia we obtained transverse velocities from the historical separation data. With… read more here.

Quantum Weak Invariants: Dynamical Evolution of Fluctuations and Correlations
Sign Up to like & getrecommendations! Published in 2020 at "Entropy"
DOI: 10.3390/e22111219
Abstract: Weak invariants are time-dependent observables with conserved expectation values. Their fluctuations, however, do not remain constant in time. On the assumption that time evolution of the state of an open quantum system is given in… read more here.
