A note on membrane interactions and the scalar potential [PDF]
Journal of High Energy Physics, 2020 We compute the tree-level potential between two parallel p-branes due to the exchange of scalars, gravitons and (p+1)-forms. In the case of BPS membranes in 4d N $$ \mathcal{N} $$ = 1 supergravity, this provides an interesting reinterpretation of the ...

Renormalization for a Scalar Field in an External Scalar Potential [PDF]
Symmetry, 2018 The Pauli–Villars regularization procedure confirms and sharpens the conclusions reached previously by covariant point splitting. The divergences in the stress tensor of a quantized scalar field interacting with a static scalar potential are isolated into a three-parameter local, covariant functional of the background potential.

Effective potential of scalar–tensor gravity [PDF]
Classical and Quantum Gravity, 2020 Abstract Effective potential of a scalar field induced by weak gravity is studied. The set of operators providing the leading contribution and preserving the second order of field equations is found. It is shown that only a mass term and a specific Brans–Dicke-like interaction are relevant within such a setup.

Generic scalar potentials in geometric scalar gravity [PDF]
Journal of Theoretical and Applied Physics, 2016 We discuss a generic form of the scalar potential appearing in the geometric scalar theory of gravity. We find the conditions on the potential by considering weak and strong gravity. The modified black hole solutions are obtained for generic potentials and the inverse problems on a black hole and on a spherical body (`pseudo-gravastar') are ...

Effects of modified woods saxon potential on quantum dynamics of spin 0 scalar particle in a cosmic string spacetime [PDF]
Scientific ReportsIn this study, we investigate the quantum dynamics of spin-0 scalar particles interacting with both scalar and vector potentials in the background of a cosmic string space-time, under the influence of a quantum flux field.

Gravitational positivity bounds on scalar potentials [PDF]
Physical Review D, 2021 We derive constraints on scalar field theories coupled to gravity by using recently developed positivity bounds in the presence of gravity. It is found that a canonically-normalized real scalar cannot have an arbitrarily flat potential unless some new physics enters well below the Planck scale.
