Journal of High Energy PhysicsIn this article we study a modification of axion physics in which the dual axion acquires a mass. This mass explicitly breaks the shift symmetry of the dual axion. The potential breaking of this shift symmetry poses a dual axion quality problem. When the

Generalization of instanton-induced inflation and dynamical compactification
Journal of High Energy Physics, 2023 It was shown that Yang-Mills instantons on an internal space can trigger the expansion of our four-dimensional universe as well as the dynamical compactification of the internal space.

False vacuum decay of excited states in finite-time instanton calculus
Journal of High Energy PhysicsExtracting information about a system’s metastable ground state energy employing functional methods usually hinges on utilizing the late-time behavior of the Euclidean propagator, practically impeding the possibility of determining decay widths of ...

On catalyzed vacuum decay around a radiating black hole and the crisis of the electroweak vacuum
Journal of High Energy Physics, 2020 False vacuum decay is a key feature in quantum field theories and exhibits a distinct signature in the early Universe cosmology. It has recently been suggested that the false vacuum decay is catalyzed by a black hole (BH), which might cause the ...

Dynamically assisted Sauter-Schwinger effect — non-perturbative versus perturbative aspects
Journal of High Energy Physics, 2017 The Sauter-Schwinger effect predicts the creation of electron-positron pairs out of the quantum vacuum by a strong and slowly varying electric field.

Journal of High Energy Physics, 2022 We study static solutions of the standard Skyrme model with a pion mass. Using approximately 105 pseudo-random initial configurations made of single Skyrmions in the non-symmetrized product Ansatz and an automatic detection of repeated solutions, we find

Skyrmions in models with pions and rho mesons
Journal of High Energy Physics, 2018 A problem with the standard Skyrme model is that Skyrmion binding energies are around 15%, being much larger than the order 1% binding energies of the nuclei that they aim to describe.

A falling magnetic monopole as a holographic local quench
Journal of High Energy Physics, 2021 An analytic static monopole solution is found in global AdS4, in the limit of small backreaction. This solution is mapped in Poincaré patch to a falling monopole configuration, which is dual to a local quench triggered by the injection of a condensate ...

Kink dynamics in a parametric ϕ 6 system: a model with controllably many internal modes
Journal of High Energy Physics, 2017 We explore a variant of the ϕ 6 model originally proposed in Phys. Rev. D 12 (1975) 1606 as a prototypical, so-called, “bag” model in which domain walls play the role of quarks within hadrons.

Soliton solutions of the fermion-Skyrmion system in (2+1) dimensions
Journal of High Energy Physics, 2018 We study effects of backreaction of the fermionic modes localized by the baby Skyrmion in the (2+1)-dimensional Skyrme model. It is shown that there is a tower of fermionic modes of two different types, localized by the soliton, however there is only one
