Scalar field dark matter and the Higgs field
Physics Letters B, 2016 We discuss the possibility that dark matter corresponds to an oscillating scalar field coupled to the Higgs boson. We argue that the initial field amplitude should generically be of the order of the Hubble parameter during inflation, as a result of its ...

Quantum imploding scalar fields [PDF]
Royal Society Open Science, 2018 The d’Alembertian □ ϕ = 0 has the solution ϕ = f ( v )/ r , where f is a function of a null coordinate v , and this allows creation of a divergent singularity out of nothing.

Physics Letters B, 2018 Nous obtenons un sous-groupe du groupe d'isométrie de pAdS (une version p-adique de AdS alternative à l'arbre Bruhat–Tits). Nous proposons un candidat pour l'action en vrac scalaire et l'équation de mouvement sur pAdS, et élaborons des expressions analytiques des fonctions du Vert pour un choix particulier de paramètre avec un ansatz pour les cas ...

A late time acceleration of the universe with two scalar fields : many possibilities [PDF]
, 2006 In the present work, an attempt has been made to explain the recent cosmic acceleration with two mutually interacting scalar fields, one being the Brans-Dicke scalar field and the other a quintessence scalar field.

Quantization of Einstein-aether scalar field cosmology
European Physical Journal C: Particles and Fields, 2021 We present, for the first time, the quantization process for the Einstein-aether scalar field cosmology. We consider a cosmological theory proposed as a Lorentz violating inflationary model, where the aether and scalar fields interact through the ...

Dissipation dynamics of a scalar field
Physical Review D, 2023 We investigate the dissipation rate of a scalar field in the vicinity of the phase transition and the ordered phase, specifically within the universality class of model A. This dissipation rate holds significant physical relevance, particularly in the context of interpreting effective potentials as inputs for dynamical transport simulations, such as ...

Collapse of an axion scalar field
European Physical Journal C: Particles and Fields, 2021 The manuscript deals with an interacting scalar field that mimics the evolution of the so-called axion scalar dark matter or axion like particles with ultra-light masses.

R2 quantum corrected scalar field inflation
Nuclear Physics B, 2022 String theory enjoys an elevated role among quantum gravity theories, since it seems to be the most consistent UV completion of general relativity and the Standard Model.

Global existence and future asymptotic behaviour for solutions of the Einstein-Vlasov-scalar field system with surface symmetry [PDF]
, 2005 We prove in the cases of plane and hyperbolic symmetries a global in time existence result in the future for comological solutions of the Einstein-Vlasov-scalar field system, with the sources generated by a distribution function and a scalar field ...
