Curvature corrections to the capillary wave Hamiltonian

  • Published:
Zeitschrift für Physik B Condensed Matter

Abstract

The fluctuations of interfaces between fluid phases are governed by an effective nonlocal interface Hamiltonian whose gradient expansion leads to the Helfrich Hamiltonian. Based on density functional theory we discuss the validity of this expansion and study the expansion coefficients multiplying the corresponding curvature terms.
