1. Strong Correlation Effects in Bosonic and Fermionic Systems Through an Unbiased Quantum Monte Carlo Approach
Abstract : Strongly interacting many-body quantum systems constitute some of the most challenging problems in physics, and exact analytical solutions are rare. In this thesis, we will investigate the models of two such systems numerically using the unbiased worm-algorithm Monte Carlo method. READ MORE

2. Interacting Dirac Matter
Abstract : The discovery of graphene in 2004 has led to a surge of activities focused on the theoretical and experimental studies of materials hosting linearly dispersive quasiparticles during the last decade. Rapid expansion in the list of materials having similar properties to graphene has led to the emergence of a new class of materials known as the Dirac materials. READ MORE

3. Numerical solutions to non-linear inhomogeneous problems in Superconductivity : From sphalerons to multi-band boundary states and spontaneous magnetic fields
Abstract : This thesis is a compilation of theoretical works focused on simulating and studying open questions regarding single and multiband superconductivity. In the last decades, with the discovery of multiband superconductors, the spectrum of potential applications has greatly widened. READ MORE

4. Spin ice under uniaxial pressure and magnetic frustration in garnets
Abstract : Frustration is the inability to simultaneously satisfy all interactions. The interest in magnetic frustration has grown during the last decades. The research has among other findings been promoted by the discovery of spin ice which is a frustrated magnetic compound with an exotic ground state and unusual excitations. READ MORE

5. Developing semi-empirical ab initio based potentials in materials modeling
Abstract : Ab initiocalculation based on density function theory (DFT) is an accu-rate and efficient method for modelling material properties. It is performedby solving the Shrödinger equations with a few assumptions to obtain thephysical properties of the system. It is very computational demanding whendealing with large systems or long-time simulations. READ MORE
