Moduli spaces of instantons on the Taub-NUT space

SA Cherkis - Communications in Mathematical Physics, 2009 - Springer
We present ADHM-Nahm data for instantons on the Taub-NUT space and encode these
data in terms of Bow Diagrams. We study the moduli spaces of the instantons and present …

NUT solutions in Einstein-Maxwell-scalar-Gauss-Bonnet gravity

M Butler, AM Ghezelbash - Physical Review D, 2024 - APS
In this article, we consider a class of four-dimensional Einstein-Maxwell theory which is
coupled nonminimally to a scalar field and the Gauss-Bonnet invariant. We mainly use the …

Exact helicoidal and catenoidal solutions in five-and higher-dimensional Einstein-Maxwell theory

AM Ghezelbash, V Kumar - Physical Review D, 2017 - APS
We present several new exact solutions in five-and higher-dimensional Einstein-Maxwell
theory by embedding the Nutku instanton. The metric functions for the five-dimensional …

Non-Abelian pp-waves in D= 4 supergravity theories

M Cariglia, GW Gibbons, R Güven… - Classical and Quantum …, 2004 - iopscience.iop.org
The non-Abelian plane waves, first found in flat spacetime by Coleman and subsequently
generalized to give pp-waves in Einstein–Yang–Mills theory, are shown to be …

Harmonic functions and instanton moduli spaces on the multi-Taub–NUT space

G Etesi, S Szabó - Communications in mathematical physics, 2011 - Springer
Explicit construction of the basic SU (2) anti-instantons over the multi-Taub–NUT geometry
via the classical conformal rescaling method is exhibited. These anti-instantons satisfy the …

Orbifold instantons, moment maps, and Yang-Mills theory with sources

TA Ivanova, O Lechtenfeld, AD Popov, RJ Szabo - Physical Review D …, 2013 - APS
We revisit the problem of constructing instantons on ADE orbifolds R 4/Γ and point out some
subtle relations with the complex structure on the orbifold. We consider generalized …

Homotopic classification of Yang–Mills vacua taking into account causality

G Etesi - International Journal of Theoretical Physics, 2007 - Springer
Existence of θ-vacuum states in Yang–Mills theories defined over asymptotically flat space-
times examined taking into account not only the topology but the complicated causal …
