1. Interactions and dynamics in biophysical model systems
Sammanfattning : Computer simulations of simplified model systems provide understanding of how complex biological systems behave. The simulations give detailed information about the systems, with atomistic resolution, that can be used in combination with experimental knowledge to shed light on underlying physical principles. LÄS MER
2. Molecular Dynamics Simulations of Fluid Lipid Membranes
Sammanfattning : Lipid molecules form thin biological membranes that envelop all living cells, and behave as two-dimensional liquid sheets immersed in bulk water. The interactions of such biomembranes with their environment lay the foundation of a plethora of biological processes rooted in the mesoscopic domain - length scales of 1-1000 nm and time scales of 1-1000 ns. LÄS MER
3. Dispersion Corrections at Planar Surfaces
Sammanfattning : When simulating a molecular system, a cutoff distance for interactions is often used to speed up the simulations. This is made at the cost of neglecting some interactions which will lead to inaccurate results for energy, pressure components and surface tension (for systems with surfaces). LÄS MER
4. Classical and Quantum Descriptions of Proteins, Lipids and Membranes
Sammanfattning : In this thesis the properties of proteins and membranes are studied by molecular dynamics simulations. The subject is decomposed into parts addressing free energy calculations in proteins, mechanical inclusion models for lipid bilayers, phase transitions and structural correlations in lipid bilayers and atomistic lipid bilayer models. LÄS MER
5. Atomistic computer simulations of lipid bilayers
Sammanfattning : Computer simulation has become an important tool for the study of biomolecular systems. This thesis deals with molecular dynamics simulations of one-component lipid bilayers, which may serve as models for biological membranes. LÄS MER
