Non-Abelian strings and domain walls in two Higgs doublet models
A bstract Contrary to the standard model that does not admit topologically nontrivial solitons,
two Higgs doublet models admit topologically stable vortex strings and domain walls. We …

Quark-hadron continuity under rotation: Vortex continuity or boojum?
Quark-hadron continuity was proposed as a crossover between hadronic matter and quark
matter without a phase transition, based on the matching of the symmetries and excitations …
