To realize first-order electroweak phase transition, it is necessary to generate a barrier in the thermal Higgs potential, which is usually triggered by scalar degree of freedom. We instead investigate phase transition patterns in pure fermion extensions of the standard model, and find that additional fermions with mass hierarchy and mixing could develop such barrier and realize strongly first-order phase transition in such models. In the Higgs potential with polynomial parametrization, the barrier can be generated in the following two patterns: (I) positive quadratic term, negative cubic term and positive quartic term or (II) positive quadratic term, negative quartic term and positive higher dimensional term, such as dimensional 6 operator.

Singlet-Doublet fermion origin of dark matter, neutrino mass and inverse first-order electroweak phase transition
New singlet and doublet fermions, a scalar singlet, and right-handed neutrinos can simultaneously explain Dirac neutrino masses, dark matter, and a two-step inverse electroweak phase transition with observable gravita...

Polyakov Loops Tame Phase Transitions
Polyakov loop contributions to the thermal effective potential soften electroweak phase transitions, disfavoring first-order transitions and suppressing gravitational-wave signals.
