21. Ab Initio Investigation of Interfacial and Grain Boundary Properties of Metals and Alloys
Abstract : Phase interface (IF) and grain boundary (GB) are both common yet critical planar defects influencing the mechanical and physical properties of polycrystalline materials. Due to the complex nature of IFs and GBs in terms of structure and chemistry, determining the accurate excess energies associated with these defects is challenging for both experimental measurements and theoretical simulations.

22. Computational studies of flow in Couette Rheometer and particle interaction in non-Newtonian fluids
Abstract : This work aims to study the flow of non-Newtonian fluids and has two main goals. First, the power-law and Herschel Bulkley fluids are studied in a Couette rheometer. Second, the static and dynamic interaction of dual particles in power-law fluid are investigated. READ MORE

23. Combinatorics of solvable lattice models with a reflecting end
Abstract : I den här avhandlingen studerar vi några exakt lösbara, kvantintegrerbara gittermodeller. Izergin bevisade en determinantformel för partitionsfunktionen till sexvertexmodellen på ett gitter av storlek n × n med Korepins domänväggrandvillkor (domain wall boundary conditions – DWBC).

24. A combinatorial description of certain polynomials related to the XYZ spin chain
Abstract : The aim of this thesis is to study the connection between the three-color model and the polynomials q_n(z) of Bazhanov and Mangazeev. To give some background, we describe some exactly solvable, quantum integrable lattice models and their connections to each other and to other models. READ MORE

25. Solvable Topological Boundaries
Abstract : The hallmark of topological phases of matter is the presence of robust boundary states. In this dissertation, a formalism is developed with which analytical solutions for these states can be straightforwardly obtained by making use of destructive interference, which is naturally present in a large family of lattice models.
