Exploring the origins of high-velocity features in SNe Ia with the spectral synthesis code TARDIS
Luke Harvey, Kate Maguire, Alexander Holas +8
Appearing as secondary higher-velocity absorption components, high-velocity features (HVFs) have been observed in several absorption lines in many Type Ia supernovae (SNe Ia). The…
Understanding the invader-driven replicator dynamics
Thi Minh Thao Le, Marina Garcia-Romero, Joao Duarte Âlcantara Galvao +2
In this paper, we study a special case of the invasion fitness matrix in a replicator equation: the invader-driven case. In this replicator, each species is defined by its unique a…
Suppression of pair beam instabilities in a laboratory analogue of blazar pair cascades
Charles D. Arrowsmith, Francesco Miniati, Pablo J. Bilbao +28
The generation of dense electron-positron pair beams in the laboratory can enable direct tests of theoretical models of -ray bursts and active galactic nuclei. We have successfu…
Supersolid light in a semiconductor microcavity
J. L. Figueiredo, J. T. Mendonça, H. Terças
Supersolidity - simultaneous superfluid flow and crystalline order - has been realized in quantum atomic systems but remains unexplored in purely photonic platforms operating at we…
Searching for HWW Anomalous Couplings with Simulation-Based Inference
Marta Silva, Ricardo Barrué, Inês Ochoa +1
Understanding the source of the universe's asymmetry between matter and antimatter is one of the major open questions in particle physics. In this work, the sensitivity of novel ma…
Emergent Hydrodynamics in an Exclusion Process with Long-Range Interactions
Ali Zahra, Jerome Dubail, Gunter M. Schütz
We study the symmetric Dyson exclusion process (SDEP) - a lattice gas with exclusion and long-range, Coulomb-type interactions that emerge both as the maximal-activity limit of the…
