Spectral curves of hyperbolic monopoles from ADHM [PDF]
J.Phys.A 54, 165401 (2021), 2020 Magnetic monopoles in hyperbolic space are in correspondence with certain algebraic curves in mini-twistor space, known as spectral curves, which are in turn in correspondence with rational maps between Riemann spheres. Hyperbolic monopoles correspond to circle-invariant Yang-Mills instantons, with an identification of the monopole and instanton ...

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).

M‐Branes: Lessons from M2's and Hopes for M5's
Fortschritte der Physik, Volume 67, Issue 8-9, August-September 2019., 2019 Abstract In this talk we will review the construction of M2‐brane SCFT's highlighting some novelties and the role of 3‐algebras. Parts of our discussion will closely follow parts of [1]. Next we will discuss M5‐branes: the basics, the obstacles as well as various attempts to construct the associated SCFT and potential relations between M2‐branes and M5‐

False vacuum decay in gauge theory
Journal of High Energy Physics, 2017 The decay rate of a false vacuum is studied in gauge theory, paying particular attention to its gauge invariance. Although the decay rate should not depend on the gauge parameter ξ according to the Nielsen identity, the gauge invariance of the result of ...

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.

Topology in the Bulk: Gauge Field Solitons in Extra Dimensions [PDF]
Nucl.Phys. B596 (2001) 243-258, 2000 Certain static soliton configurations of gauge fields in 4+1 dimensions correspond to the instanton in 4-Euclidean dimensions ``turned on its side,'' becoming a monopole in 4+1. The periodic instanton solution can be used with the method of images to construct solutions satisfying D-brane boundary conditions.

Heun Functions and Some of Their Applications in Physics
Advances in High Energy Physics, Volume 2018, Issue 1, 2018., 2018 Most of the theoretical physics known today is described by using a small number of differential equations. For linear systems, different forms of the hypergeometric or the confluent hypergeometric equations often suffice to describe the system studied.

Instanton expansions and phase transitions
Journal of High Energy Physics, 2022 A central object in any axionic theory is its periodic potential, which is typically generated by instantons. The goal of this paper is to understand what physically happens to the theory when we lose control of the potential’s instanton expansion.

Supersymmetric Quantum Mechanics and Topology
Advances in High Energy Physics, Volume 2016, Issue 1, 2016., 2016 Supersymmetric quantum mechanical models are computed by the path integral approach. In the β → 0 limit, the integrals localize to the zero modes. This allows us to perform the index computations exactly because of supersymmetric localization, and we will show how the geometry of target space enters the physics of sigma models resulting in the ...

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.
