First-order phase transitions in Twin Higgs models
نویسندگان
چکیده
We revisit phase transitions in Twin Higgs (TH) models. show that strong first-order (FOPTs) can occur provided appropriate source of $\mathbb{Z}_2$ symmetry breaking between the twin and Standard Model (SM) sectors is present. found FOPTs two classes First: with hard scalar potential allowing for FOPT. Second: broken by enhanced Yukawa couplings leptons. also considered supersymmetric UV completion second scenario light sleptons. The signal gravitational waves produced during these typically small but be close to reach AEDGE Einstein Telescope case FOPT induced Our results open a way generate SM baryon asymmetry TH

Quantum first order phase transitions
The scaling theory of critical phenomena has been successfully extended for classical first order transitions even though the correlation length does not diverge in these transitions. In this paper we apply the scaling ideas to quantum first order transitions. The usefulness of this approach is illustrated treating the problems of a superconductor coupled to a gauge field and of a biquadratic H...
متن کاملFirst-order dynamical phase transitions.
Recently, dynamical phase transitions have been identified based on the nonanalytic behavior of the Loschmidt echo in the thermodynamic limit [Heyl et al., Phys. Rev. Lett. 110, 135704 (2013)]. By introducing conditional probability amplitudes, we show how dynamical phase transitions can be further classified, both mathematically, and potentially in experiment. This leads to the definition of f...
متن کاملFirst Order Phase Transitions in Gravitational Collapse
In recent numerical simulations of spherically symmetric gravitational collapse a new type of critical behaviour, dominated by a sphaleron solution, has been found. In contrast to the previously studied models, in this case there is a finite gap in the spectrum of black-hole masses which is reminiscent of a first order phase transition. We briefly summarize the essential features of this phase ...
متن کاملQuasilumps from First Order Phase Transitions
We investigated the bubble collisions during the first order phase transitions. Numerical results indicate that within the certain range of parameters the collision of two bubbles leads to formation of separate relatively long-lived quasilumps configurations filled with scalar field oscillating around the true vacuum state. Energy is perfectly localized, and density is slightly pulsating around...
متن کاملCoarse Graining and First Order Phase Transitions
We discuss the dependence of the coarse grained free energy and the classical interface tension on the coarse graining scale k. A stable range appears only if the renormalized dimensionless couplings at the critical temperature are small. This gives a quantitative criterion for the validity of computations within Langer’s theory of spontaneous bubble nucleation. Email: [email protected]...
