Stippling of 2D Scalar Fields [PDF]
IEEE Transactions on Visualization and Computer Graphics, 2019 We propose a technique to represent two-dimensional data using stipples. While stippling is often regarded as an illustrative method, we argue that it is worth investigating its suitability for the visualization domain. For this purpose, we generalize the Linde-Buzo-Gray stippling algorithm for information visualization purposes to encode continuous ...

Stability of a Noncanonical Scalar Field Model during Cosmological Date
Advances in High Energy Physics, 2016 Using the noncanonical model of scalar field, the cosmological consequences of a pervasive, self-interacting, homogeneous, and rolling scalar field are studied.

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.

On the Energy-Momentum Tensor of the Scalar Field in Scalar--Tensor Theories of Gravity [PDF]
, 1999 We study the dynamical description of gravity, the appropriate definition of the scalar field energy-momentum tensor, and the interrelation between them in scalar-tensor theories of gravity.

Fractional Scalar Field Cosmology
Fractal and FractionalConsidering the Friedmann–Lemaître–Robertson–Walker (FLRW) metric and the Einstein scalar field system as an underlying gravitational model to construct fractional cosmological models has interesting implications in both classical and quantum regimes ...

Instability of Massive Scalar Fields in Kerr-Newman Spacetime
, 2004 We investigate the instability of charged massive scalar fields in Kerr-Newman spacetime. Due to the super-radiant effect of the background geometry, the bound state of the scalar field is unstable, and its amplitude grows in time.

Massive and Massless Scalar Field and Confinement [PDF]
, 2003 Generalization of QCD motivated classical SU(2) Yang--Mills theory coupled to the scalar field is discussed. The massive scalar field, corresponding the scalar glueball, provides a confining potential for static, point-like, external sources.

Polar Quasinormal Modes of Neutron Stars in Massive Scalar-Tensor Theories
Frontiers in Physics, 2021 We study polar quasinormal modes of relativistic stars in scalar-tensor theories, where we include a massive gravitational scalar field and employ the standard Brans-Dicke coupling function. For the potential of the scalar field we consider a simple mass

Dynamical Analysis of Scalar Field Cosmologies with Spatial Curvature
The Open Journal of Astrophysics, 2016 We explore the dynamical behaviour of cosmological models involving a scalar field (with an exponential potential and a canonical kinetic term) and a matter fluid with spatial curvature included in the equations of motion.
