Spontaneous scalarization in generalized scalar-tensor theory [PDF]
Physical Review D, 2019 Spontaneous scalarization is a mechanism that endows relativistic stars and black holes with a nontrivial configuration only when their spacetime curvature exceeds some threshold. The standard way to trigger spontaneous scalarization is via a tachyonic instability at the linear level, which is eventually quenched due to the effect of non-linear terms ...

Influence of Reynolds number on coherent structure, flow transition, and evolution of the plane jet
Journal of Fluid Science and Technology, 2014 In the present study, the flow characteristics of a spatially evolving plane jet are investigated, focusing on the dynamics of coherent structure (CS), flow transition, and evolution.

The mirative and scalar meaning of even
Anglophonia, 2018 The analysis I develop here draws on the concept of mirativity (DeLancey 1987) and on Kay’s (1990) insight into the scalar nature of even. I show that even calls for the reconstruction of an implicit scale, on which the element highlighted by this ...

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.

Scalar-scalar, scalar-tensor, and tensor-tensor correlators from anisotropic inflation [PDF]
Physical Review D, 2010 We compute the phenomenological signatures of a model (Watanabe et al' 09) of anisotropic inflation driven by a scalar and a vector field. The action for the vector is U(1) invariant, and the model is free of ghost instabilities. A suitable coupling of the scalar to the kinetic term of the vector allows for a slow roll evolution of the vector vev, and ...

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 ...

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
