The Dirac Operator Spectrum and Effective Field Theory
P. H. Damgaard
When chiral symmetry is spontaneously broken, the low-energy part of the Dirac operator spectrum can be computed analytically in the chiral limit. The tool is effective field theor…

Collective Fields for QCD
P. H. Damgaard, H. B. Nielsen, R. Sollacher
A gauge-symmetric approach to effective Lagrangians is described with special emphasis on derivations of effective low-energy Lagrangians from QCD. The examples we discuss are base…
