We revisit the computation of bubble wall friction during a cosmological first-order phase transition, using an extended fluid Ansatz to solve the linearized Boltzmann equation. A singularity is found in the fluctuations of background species as the wall approaches the speed of sound. Using hydrodynamics, we argue that a discontinuity across the speed of sound is expected on general grounds, which manifests itself as the singularity in the solution of the linearized system. We discuss this result in comparison with alternative approaches proposed recently, which find a regular behaviour of the friction for all velocities.

Scalar damping in cosmological phase transitions
The scalar damping coefficient in the hydrodynamic friction term is extracted from kinetic theory for SM-like plasmas, and the runaway-wall pressure is found to bound the local friction from above.

Multi-step Strong First-Order Electroweak Phase Transitions in the Inverted Type-I 2HDM: Parameter Space, Gravitational Waves, and Collider Phenomenology
In the inverted Type-I 2HDM, one-step and two-step strong first-order electroweak phase transitions live in largely separate parameter regions, and LISA-detectable gravitational wave signals come predominantly from th...

Thermal Masses and Bubble-Wall Friction in Cosmological Phase Transitions
Including thermal masses in both the Boltzmann source and collision terms removes the infrared gauge-boson enhancement, making W-boson friction subleading in the singlet-extended Standard Model.

Strong First-Order Electroweak Phase Transitions and Gravitational Waves in the Normal Two-Higgs-Doublet Model: A Comparative Study of the Four Yukawa Types and Thermal Resummation Schemes
In the Normal 2HDM, SFOEWPTs are single-step and alignment-favoring across all four Yukawa types, yet Parwani versus Arnold–Espinosa resummation changes the viable heavy-mass range from ~1.6 TeV to ≲800 GeV and leaves...
