1. Modeling mesoscopic unconventional superconductors
Abstract : High-temperature superconducting materials are often experimentally realized as thin films that can be patterned into devices operating in the mesoscopic regime. On this length scale, various finite-size and surface effects heavily influence the nature of the superconducting state, and can induce new ground states with spontaneously broken symmetries.

2. Crystallization of the superconducting phase in unconventional superconductors
Abstract : Superconductivity is a macroscopic quantum phenomenon, in the sense that a macroscopic number of electrons form a pair condensate, that occupies a single ground state. The electrons in this state are phase-coherent, breaking global U (1)-symmetry, and spatial variations of the phase imply superflows that usually cost kinetic energy, resulting in a uniform and rigid phase.

3. The origin of symmetry in the metabolism of cancer – From systems biology to translational medicine
Abstract : Why do not we have a cure for cancer yet? Cancer is the malady of the century, the most intensely studied disease of all time. The question is puzzling. It assumes that cancer is a single entity that we can target and eradicate. READ MORE

4. Control of Quasi-Equivalence in Virus Capsids
Abstract : Many T=3 plant and insect viruses use a molecular switch in form of order/disorder of a segment of the polypeptide chain to regulate the quasi-equivalent contacts. The structure of a mutant of the T=3 capsid of bacteriophage fr confirms that this virus and other members of the Leviviridae family lack a switch mechanism. READ MORE

5. Necked-in Superdeformed Nuclei
Abstract : Superdeformation, i.e. elongated shapes with the longest axis approximately twice as long as the shorter axes, has provided many new insights in nuclear structure. In this dissertation the possibility of forming superdeformed states related to two connected spheres, having a more or less pronounced neck, is investigated. READ MORE
