Zusammenfassung

Zur Illustration der allgemeinen Überlegungen des vorigen Kapitels wollen wir nun ein Verfahren beschreiben, bei dem man die Elimination der kurzwelligen Freiheitsgrade im Impulsraum durchführt. Wir setzen für den effektiven Hamilonoperator kT c H(α) an:

$$ H = \int \left\{ {\frac{1}{2}\left[ {{{\left( {\nabla \varphi } \right)}^2} + {k^2}{\varphi ^2}} \right] + \frac{g}{4}{\varphi ^4} - h\varphi } \right\}{d^d}r. $$
