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 ...

Charge-Swapping Q-balls and Their Lifetimes

Journal of High Energy Physics, 2021
For scalar theories accommodating spherically symmetric Q-balls, there are also towers of quasi-stable composite Q-balls, called charge swapping Q-balls (CSQs).

Monopoles, sphalerons and instantons in strong magnetic fields [PDF]

, 2021
Magnetic monopoles are hypothetical particles consisting of an isolated north or south magnetic pole without a partner. Though they are currently unobserved, predictions from quantum field theory indicate that if they do exist, they should be produced in

Revisit on two-dimensional self-gravitating kinks: superpotential formalism and linear stability

Journal of High Energy Physics, 2021
Self-gravitating kink solutions of a two-dimensional dilaton gravity are revisited in this work. Analytical kink solutions are derived from a concise superpotential formalism of the dynamical equations.

Exact WKB analysis of the vacuum pair production by time-dependent electric fields

Journal of High Energy Physics, 2021
We study the vacuum pair production by a time-dependent strong electric field based on the exact WKB analysis. We identify the generic structure of a Stokes graph for systems with the vacuum pair production and show that the number of produced pairs is ...

Topological solitons [PDF]

, 2004
Topological solitons occur in many nonlinear classical field theories. They are stable, particle-like objects, with finite mass and a smooth structure. Examples are monopoles and Skyrmions, Ginzburg-Landau vortices and sigma-model lumps, and Yang-Mills ...

Singular Pöschl-Teller II potentials and gravitating kinks

Journal of High Energy Physics, 2022
We report a two-dimensional (2D) gravitating kink model, for which both the background field equations and the linear perturbation equation are exactly solvable.

Infinite-Centre Gibbons-Hawking Metrics, Applied to Gravitational Instantons and Monopoles [PDF]

, 2010
We investigate the convergence of infinite-centre Gibbons-Hawking metrics, in the contexts of four-dimensional gravitational instantons and their applications, Kaluza-Klein monopoles and vortices, gravitational calorons, analytical extensions of Majumdar-

Exact quantization and analytic continuation

Journal of High Energy Physics, 2023
In this paper we give a streamlined derivation of the exact quantization condition (EQC) on the quantum periods of the Schrödinger problem in one dimension with a general polynomial potential, based on Wronskian relations.
