1. Ab initio Lattice Dynamics : Hydrogen-dense and Other Materials
Abstract : This thesis presents a theoretical study of materials under high pressure using ab initio lattice dynamics based on density functional theory and density functional perturbation theory using both super-cell and linear response approach. Ab initio lattice dynamics using super-cell approach is applied to compare our theoretical predictions with experimental findings. READ MORE

4. Exploring magnetocaloric materials by ab-initio methods
Abstract : This thesis explores the characterization of magnetocaloric materials from first-principles calculations, emphasizing entropy variation associated with the magnetocaloric effect. The study happens in the context of the search for new magnetocaloric materials to be applied in domestic magnetic refrigerators, as environmentally friendly and energy-efficient alternatives to conventional vapor-compression devices.
