When fluctuating fields are confined between two surfaces, long-range forces arise. A
famous example is the quantum-electrodynamical Casimir force that results from zero-point …

This chapter reviews the physical or intermolecular interaction, including van der Waals
interaction and hydrogen bonding. Moreover, it is transformed in the London force as a …

The current knowledge about fluctuation-induced long-ranged forces is summarized.
Reference is made in particular to fluids near critical points, for which some new insight has …

The following sections are included: Preliminaries Principles of Statistical Mechanics
Thermodynamic limit Equivalence of Gibbs ensembles Phase transitions Order parameter …

We report dielectric constant measurements showing critical fluctuation-induced thinning of
4 He films near the superfluid transition. The films are adsorbed on a stack of copper …

The critical Casimir force (CF) is observed in thin wetting films of a binary liquid mixture
close to the liquid/vapor coexistence. X-ray reflectivity shows thickness (L) enhancement …

We investigate the behavior of colloidal particles immersed in a binary liquid mixture of
water and<? format?> 2, 6-lutidine in the presence of a chemically patterned substrate …

The Casimir force between macroscopic bodies depends strongly on their shape and
orientation. To study this geometry dependence in the case of two deformed metal plates …

We present new capacitance measurements of critical Casimir force-induced thinning of He
4 films near the superfluid transition, focused on the region below T λ where the effect is the …

We present capacitance measurements of the equilibrium thickness of 3 He− 4 He mixture
films as a function of temperature and concentration. The films are adsorbed on a Cu …
