A lattice model of hydrophobic interactions
Daniel W. Hone, P.A. Pincus
TL;DR
This paper presents a lattice model for hydrophobic interactions based on hydrogen bonding as proton exchange, using techniques from electron correlation theory to match observed water-impurity behaviors.
Contribution
It introduces a novel lattice model for hydrophobic interactions that incorporates hydrogen bonding via proton exchange, bridging concepts from electron correlation theory.
Findings
Model reproduces observed magnitudes of hydrophobic interactions.
Captures temperature dependence of water-impurity interactions.
Provides a theoretical framework for understanding hydrogen bonding in water.
Abstract
Hydrogen bonding is modeled in terms of virtual exchange of protons between water molecules. A simple lattice model is analyzed, using ideas and techniques from the theory of correlated electrons in metals. Reasonable parameters reproduce observed magnitudes and temperature dependence of the hydrophobic interaction between substitutional impurities and water within this lattice.
