Quantum aspects of Yukawa model with scalar and axial scalar fields in curved spacetime

European Physical Journal C: Particles and Fields, 2019
We study the Yukawa model with one scalar and one axial scalar fields, coupled to N copies of Dirac fermions, in curved spacetime background. The theory possesses a reach set of coupling constants, including the scalar terms with odd powers of scalar ...

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 ...

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,

UV/IR Mixing for Noncommutative Complex Scalar Field Theory, II (Interaction with Gauge Fields)

, 2000
We consider noncommutative analogs of scalar electrodynamics and N=2 D=4 SUSY Yang-Mills theory. We show that one-loop renormalizability of noncommutative scalar electrodynamics requires the scalar potential to be an anticommutator squared.

Construction of RG improved effective potential in a two real scalar system [PDF]

, 2019
We study the improvement of effective potential by renormalization group (RG) equation in a two real scalar system. We clarify the logarithmic structure of the effective potential in this model.

An Underwater Passive Electric Field Positioning Method Based on Scalar Potential

Mathematics
In order to fulfill the practical application demands of precisely localizing underwater vehicles using passive electric field localization technology, we propose a scalar-potential-based method for the passive electric field localization of underwater ...

Non-perturbative fixed points and renormalization group improved effective potential

Physics Letters B, 2014
The stability conditions of a renormalization group improved effective potential have been discussed in the case of scalar QED and QCD with a colorless scalar.

Higuchi bound on slow-roll inflation and the swampland

Journal of High Energy Physics, 2020
In this paper we study the implications of the generalized Higuchi bound on massive spin-two fields for the derivative of the scalar potential within bimetric theory.

A complex singlet extension of the standard model and multi-critical point principle

Physics Letters B, 2023
We study the Multi-critical Point Principle (MPP) in a complex singlet scalar extension of the Standard Model (CxSM). The MPP discussed in this study selects model parameters so that two low-energy vacua realized by scalar fields are degenerate.
