Transition metal dichalcogenides (TMDs) are layered materials that, due to their reduced dimensionality, host interesting phases such as charge density waves (CDW) and superconductivity. Due to the layered structure, these materials can be intercalated with magnetic ions resulting in suppression of CDW/superconductivity in favor of different magnetic ground states. Furthermore, the wealth of phases that this family of materials hosts lies in the possibility of combining different chemical elements which build them. All these phases are relatively easy to influence by intercalation as well as by applying external pressure. The aim of the project is to better understand the magnetism of these materials as well as the processes that dominate electric transport in these systems and to understand to what extent they are similar / different from heavy fermionic compounds, unconventional superconductors and topological materials.
Several aspects of TMD are intertwined in the project: first, (relatively) long range magnetic interactions, and interactions of magnetic and metallic degrees of freedom. The second is the effect of uniaxial and hydrostatic pressure on ground states. The third is the effect of disorder on the ground states of TMD and finally, the topological aspects of TMDs.
