LeWRON is a new agentic framework that automates construction, auditing, and exploration of finite-temperature effective potentials and gravitational-wave predictions for electroweak phase transitions starting from an input Lagrangian.
Dynamical LTE simulations reveal that heating wave formation often outlasts wall acceleration, yielding a revised maximal driving pressure criterion that weakens hydrodynamic obstruction compared to steady-state models.
Filtered Dark Matter hydrodynamics during first-order phase transitions is modeled as a two-component fluid, yielding detonation-like and deflagration-like solutions in ballistic and local thermal equilibrium regimes that change relic abundance predictions.
Precision study of dark sector phase transitions finds PTA-favored parameters near EFT breakdown with disfavored GW signals after higher-order corrections.
Dark sector first-order phase transitions near 10 MeV can substantially modify vector dark matter relic densities away from standard thermal freeze-out predictions, with distinct mass windows and calculable gravitational wave backgrounds.
TransitionListener v2.0 supplies an end-to-end pipeline from scalar potential to gravitational wave spectra with improved handling of transition dynamics and bubble separation.
