Hyperbolic inflationary model with nonzero curvature
Physics Letters B, 2022 We consider a cosmological model consisting of two scalar fields defined in the hyperbolic plane known as hyperbolic inflation. For the background space, we consider a homogeneous and isotropic spacetime with nonzero curvature.

Mixing and Isosurface Geometry in Turbulent Transverse Jets [PDF]
, 2001 Mixing and the geometry of jet-fluid-concentration level sets in turbulent transverse jets were experimentally studied. Jet-fluid concentration fields were measured with laser-induced fluorescence and digital imaging techniques for Reynolds numbers ...

Dynamics in Interacting Scalar-Torsion Cosmology
Universe, 2021 In a spatially flat Friedmann–Lemaître–Robertson–Walker background space, we consider a scalar-torsion gravitational model which has similar properties to the dilaton theory. This teleparallel model is invariant under a discrete transformation similar to

Scalar hairy black holes in Einstein-Maxwell-conformally coupled scalar theory
Physics Letters B, 2020 We obtain scalar hairy black holes from Einstein-Maxwell-conformally coupled scalar (EMCS) theory with the scalar coupling parameter α to the Maxwell term.

Mixing among lowest-lying scalar mesons and scalar glueball
Nuclear Physics B, 2018 Scalar glueball is implemented in single nonet linear sigma model (SNLSM) which basically includes lowest lying scalar and pseudoscalar mesons. Our new version of SNLSM involves mixing among scalar matter fields and glueball field which is enforced by ...

Note on scalar–graviton and scalar–photon–graviton amplitudes
European Physical Journal C: Particles and Fields, 2020 In this short note, we propose an algorithm based on the expansions of amplitudes, the dimensional reduction technique and the approach by differential operators, to calculate the tree level scalar–graviton amplitudes with two massive scalars and the ...

ϕ-modes of neutron stars in a massless scalar–tensor theory
Frontiers in Astronomy and Space Sciences, 2022 Scalar–tensor theories allow for a rich spectrum of quasinormal modes of neutron stars. The presence of the scalar field allows for polar monopole and dipole radiation, as well as for additional higher multipole modes led by the scalar field.
