Large scale and large period limits of symmetric calorons

Understand

We construct SU(2) calorons, with non-trivial holonomy, instanton charge 2 and magnetic charge 0 or -1; these calorons have two constituent monopoles, with charges (2,2) or (2,1).

• Our calorons are U(1)-symmetric and are constructed via the Nahm transform.
• They fall into distinct families which can be classified using representation theory.
• We consider large scale and large period limits of these calorons; in particular, the large scale limit may be a monopole, or a caloron with different topological charges.
