Multi-Calorons Revisited
Full text linkAnalytic Nahm data is re-examined for SU(2) calorons, or periodic instantons,
of instanton charge 2. The Nahm equations are solved analytically in terms of
Jacobi elliptic functions and the possible matching conditions are classified.
The dimensions of framed moduli space for charge 2 caloron is enumerated and
the maximal parameter, which is 16 for charge 2, case is identified. The
monopole and instanton limits are also considered. It is found that the Nahm
data which does not correspond to the standard monopoles plays significant role
for calorons.Comment: 29 pages, 3 figures, published versio
