The scalar potential in noncommutative geometry [PDF]
Physics Letters B, 1996 We present a derivation of the general form of the scalar potential in Yang-Mills theory of a non-commutative space which is a product of a four-dimensional manifold times a discrete set of points. We show that a non-trivial potential without flat directions is obtained after eliminating the auxiliary fields only if constraints are imposed on the mass ...

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

Construction of inflationary scenarios with the Gauss–Bonnet term and nonminimal coupling
European Physical Journal C: Particles and Fields, 2021 Inflationary models with a scalar field nonminimally coupled both with the Ricci scalar and with the Gauss–Bonnet term are studied. We propose the way of generalization of inflationary scenarios with the Gauss–Bonnet term and a scalar field minimally ...

Effect of Medium on Fundamental Interactions in Gravity and Condensed Matter
Frontiers in Physics, 2022 Recently, it was shown that the gravitational field undergoes exponential cutoff at large cosmological scales due to the presence of background matter. In this article, we demonstrate that there is a close mathematical analogy between this effect and the

Symmetries and mass degeneracies in the scalar sector
Journal of High Energy Physics, 2019 We explore some aspects of models with two and three SU(2) scalar doublets that lead to mass degeneracies among some of the physical scalars. In Higgs sectors with two scalar doublets, the exact degeneracy of scalar masses, without an artificial fine ...

Effective Scalar Potential in Asymptotically Safe Quantum Gravity
Universe, 2021 We compute the effective potential for scalar fields in asymptotically safe quantum gravity. A scaling potential and other scaling functions generalize the fixed point values of renormalizable couplings. The scaling potential takes a non-polynomial form,

European Physical Journal C: Particles and Fields, 2021 The superradiant stability of a Kerr–Newman black hole and charged massive scalar perturbation is investigated. We treat the black hole as a background geometry and study the equation of motion of the scalar perturbation.

Non-minimal two-loop inflation
Physics Letters B, 2015 We investigate the chaotic inflationary model using the two-loop effective potential of a self-interacting scalar field theory in curved spacetime. We use the potential which contains a non-minimal scalar curvature coupling and a quartic scalar self ...

Nuclear Physics B, 2021 We present a modified version of the Koide formula from a scalar potential model or from a Yukawaon model, based on scalar fields set up in a nonet representation of the SU(3) flavor symmetry in the Standard Model.
