    "abstract": "In order to elucidate the enhancement of pion production that may occur\nduring dynamical scenarios of interest in connection with disoriented chiral\ncondensates, we study the evolution of boson modes whose frequencies have a\ngiven arbitrary time dependence. The quantum-field treatment yields expressions\nfor the time dependence of observables that depend only on the initial state\nand specific state-independent enhancement coefficients which can be obtained\nfrom the given evolution of the frequency. It is shown how these coefficients\nalso can be obtained within an entirely classical framework by judicious usage\nof the dependence of the resulting enhancement on the phase of the initial\nstate. Illustrative application is made for frequency evolutions obtained from\nidealized simulations of high-energy heavy-ion collisions and it is shown how\nthe non-equilibrium evolution of the order parameter may lead to significant\nenhancements in the final pion spectra.",
