Rotational Invariance and the Theory of Directed Polymer Nematics
Randall D. Kamien, Pierre Le Doussal, David R. Nelson
Abstract
The consequences of rotational invariance in a recent theory of fluctuations in dilute polymer nematics are explored. A correct rotationally invariant free energy insures that anomalous couplings are not generated in a one-loop renormalization group calculation.
