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. High-efficiency dissipative Kerr solitons in microresonators
Sammanfattning : The microresonator comb (microcomb) is a laser source that generates equally spaced coherent lines in the spectral domain. Having a chip-scale size and the potential of being low cost, it has attracted attention in multiple applications. LÄS MER
3. Dissipative Kerr solitons in normal dispersion waveguides
Sammanfattning : The microresonator comb (microcomb) is a laser source which generatesequally spaced coherent lines in the spectral domain. Having a miniaturefootprint and the potential of being low cost, it has attracted attention inmultiple applications. LÄS MER
4. Generation and Transmission of Optical Solitons at Ultrahigh Bit Rates
Sammanfattning : This thesis deals with the generation and transmission of optical solitons in ultrahigh-speed fiber-optic communication systems. For optical soliton pulses the fiber dispersion and nonlinearity can under certain circumstances cancel each other, thus allowing the solitons to remain undistorted over long distances. LÄS MER
5. 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
