Instantons and constituent monopoles
Falk Bruckmann, Daniel Nogradi, Pierre van Baal
We review how instanton solutions at finite temperature can be seen as boundstates of constituent monopoles, discuss some speculations concerning their physical relevance and the l…
Chiral zero-mode for abelian BPS dipoles
Pierre van Baal
We present an exact normalisable zero-energy chiral fermion solution for abelian BPS dipoles. For a single dipole, this solution is contained within the high temperature limit of t…
Abelian projected monopoles - to be or not to be
Pierre van Baal
We analyse what happens with two merging constituent monopoles for the SU(3) caloron. Identified through degenerate eigenvalues (the singularities or defects of the abelian project…
Overlapping Instantons
M. Garcia Perez, T. G. Kovacs, P. van Baal
Overlapping instantons have an action density profile that significantly deviates from the simple addition of the density profiles of single instantons. This turns out to have impo…
Gribov ambiguities and the fundamental domain
Pierre van Baal
This lecture is dedicated to the memory of Vladimir Gribov. We discuss the procedure of complete gauge fixing to avoid Gribov copies, as well as results for the low-lying glueball…
Intermediate Volumes and the Role of Instantons
Pierre van Baal
We review recent results for the low-lying glueball spectrum on the three-sphere in intermediate volumes that incorporate instanton effects. The latter are implemented through boun…
