The metamorphosis of semi-classical mechanisms of confinement: from monopoles on ℝ 3 × S 1 to center-vortices on ℝ 2 × T 2

open access: yesJournal of High Energy Physics
There are two distinct regimes of Yang-Mills theory where we can demonstrate confinement, the existence of a mass gap, and the multi-branch structure of the effective potential as a function of the theta angle using a reliable semi-classical calculation.

Instabilities of gauged Q-balls

open access: yesJournal of High Energy Physics
We present the first analytical calculation that shows that perturbations with angular dependence can lead to an instability in gauged Q-balls. We find an explicit condition on the parameters for the Q-ball to become unstable.

On the EFT of dyon-monopole catalysis

open access: yesJournal of High Energy Physics
Monopole-fermion (and dyon-fermion) interactions provide a famous example where scattering from a compact object gives a cross section much larger than the object’s geometrical size.

Highly-enhanced propagation of long-range kinks in heterogeneous media

open access: yesJournal of High Energy Physics
We investigate a field-theoretical model that describes the interaction between kinks and antikinks and between kinks and other heterogeneous fields and impurities.
