Low dimensional materials have been a major subject of interest in recent years. In particular, the transitions metal dichalcogenides (TMDs), quasi-2D layered materials with weak van der Waals coupling between layers, received a lot of attention. TMDs exhibit strong electron-electron and electron-phonon interactions that lead to complicated phase diagrams showing a variety of ground states.
In this talk I will describe the different types of TaS2. I will show evidence of a quantum spin liquid state in 1T-TaS2 and of topological superconductivity in 4Hb-TaS2.
