Molecular theory of hydrophobic mismatch between lipids and peptides
Daniel Duque, Xiao-jun Li, Kirill Katsov +1
Effects of the mismatch between the hydrophobic length, d, of transmembrane alpha helices of integral proteins and the hydrophobic thickness, D_h, of the membranes they span are st…
Theory of tunable pH sensitive vesicles of anionic and cationic lipids or anionic and neutral lipids
Xiao-jun Li, M. Schick
The design of vesicles which become unstable at an easily tuned value of pH is of great interest for targeted drug delivery. We present a microscopic theory for two forms of such v…
Phenomenological Theory for Phase Turbulence in Rayleigh-Bénard Convection
Xiao-jun Li, Hao-wen Xi, J. D. Gunton
We present a phenomenological theory for phase turbulence (PT) in Rayleigh-Bénard convection, based on the generalized Swift-Hohenberg model. We apply a Hartree-Fock approximation…
Fluctuations in mixtures of lamellar- and nonlamellar-forming lipids
Xiao-jun Li, M. Schick
We consider the role of nonlamellar-forming lipids in biological membranes by examining fluctuations, within the random phase approximation, of a model mixture of two lipids, one o…
Distribution of lipids in non-lamellar phases of their mixtures
Xiao-jun Li, M. Schick
We consider a model of lipids in which a head group, characterized by its volume, is attached to two flexible tails of equal length. The phase diagram of the anhydrous lipid is obt…
Theory of Lipid Polymorphism: Application to Phosphatidylethanolamine and Phosphatidylserine
Xiao-jun Li, M. Schick
We introduce a microscopic model of a lipid with a charged headgroup and flexible hydrophobic tails, a neutral solvent, and counter ions. Short-ranged interactions between hydrophi…
Nature of Roll to Spiral-Defect-Chaos Transition
Xiao-jun Li, Hao-wen Xi, J. D. Gunton
We investigate the nature of the parallel-roll to spiral-defect-chaos (SDC) transition in Rayleigh-Benard convection, based on the generalized Swift-Hohenberg model. We carry out e…
Phenomenological Theory for Spatiotemporal Chaos in Rayleigh-Benard Convection
Xiao-jun Li, Hao-wen Xi, J. D. Gunton
We present a phenomenological theory for spatiotemporal chaos (STC) in Rayleigh-Benard convection, based on the generalized Swift-Hohenberg model. We apply a random phase approxima…
Direct Transition to Spatiotemporal Chaos in Low Prandtl Number Fluids
Hao-wen Xi, Xiao-jun Li, J. D. Gunton
We present the first large scale numerical simulation of three-dimensional Rayleigh-Bénard convection near onset, under free-free boundary conditions for a fluid of Prandtl number…
Dynamical Properties of Multi-Armed Global Spirals in Rayleigh-Benard Convection
Xiao-jun Li, Hao-wen Xi, J. D. Gunton
Explicit formulas for the rotation frequency and the long-wavenumber diffusion coefficients of global spirals with arms in Rayleigh-Benard convection are obtained. Global spira…
