1. Aspects of Yang-Mills Theory : Solitons, Dualities and Spin Chains
Sammanfattning : One of the still big problems in the Standard Model of particle physics is the problem of confinement. Quarks or other coloured particles have never been observed in isolation. Quarks are only observed in colour neutral bound states. The strong interactions are described using a Yang-Mills theory. LÄS MER
2. Dynamics of Discrete Curves with Applications to Protein Structure
Sammanfattning : In order to perform a specific function, a protein needs to fold into the proper structure. Prediction the protein structure from its amino acid sequence has still been unsolved problem. The main focus of this thesis is to develop new approach on the protein structure modeling by means of differential geometry and integrable theory. LÄS MER
3. Linking Chains Together : String Bits and the Bethe Ansatz
Sammanfattning : This thesis is divided into two parts. In the first part we focus mainly on certain aspects of the AdS/CFT correspondence. The AdS/CFT correspondence is a proposed duality between Type IIB superstring theory on AdS5 x S5 and N = 4 supersymmetric Yang-Mills theory. LÄS MER
4. Bending, Twisting and Turning : Protein Modeling and Visualization from a Gauge-Invariance Viewpoint
Sammanfattning : Proteins in nature fold to one dominant native structure. Despite being a heavily studied field, predicting the native structure from the amino acid sequence and modeling the folding process can still be considered unsolved problems. In this thesis I present a new approach to this problem with methods borrowed from theoretical physics. LÄS MER
5. Protein Folding Simulations in Kink Model
Sammanfattning : The structure of protein is essentially important for life activities. Proteins can perform their functions only by specific structures. In this thesis, the kink and multi-kink model for protein description are reviewed. LÄS MER
